The MAKITA 18V LXT LITHIUM-ION SUB-COMPACT BRUSHLESS CORDLESS COMBO KIT (1.5AH) (4-PIECE) is a great starter set of power towels for beginners as well as experts. The tools are very reliable, accurate and stable. The saw is one of the best sawsof its types on the market and the battery last a long time. I like the flash light because it is bright and ligts up a good size area. The drills are compact and easy to use in tight spaces. The batteries charge fast and last. This is an outstanding combination.

(What's this)
Amazingly powerful for as small as the motors are. I wanted the hammer drill option and it works fine. I never thought about the flashlight that came as part of the set and so I’m surprised every time I use it. I find myself adjusting the head on the light snd setting it someplace where it will light up my project. Handy option I didn’t think I’d user at all but I do. The batteries that came with the set don’t have charge level light bars. The work light that comes on with a trigger squeeze doesn’t light up anything closer than 3” in front of the drill. The impact driver lights up the bit far closer to the tool. I’ve always liked magnets on the handles to hold screws or bits. I added those on this set. (See pictures) I love the belt or pocket hooks on the tools. That I’ll use frequently.

Seeds Program Review
(What's this)
Subcompact does not exactly describe size of the ¼ inch impact driver and the drill/driver/hammer drill. Yes, that’s right, a hammer-drill, which is a little larger than the size of two D-side battery cells. While the impact driver is about the size of one (!) D-size battery. Both drivers are exceptionally light weight and have powerful 18V brushless motors. The lighter weight means less fatigue and getting the job done faster. The impact driver features a unique Assist Mode (A-mode) which helps to eliminate "screw cam-out" and "cross threading" by driving at low speed until impact begins. They both have a bright double LED light and are both variable speed with the drill-driver additionally having a two speed transmission. The kit includes a bright 4-LED flashlight and a 6-1/2 inch brushless 5,000 RPM circular saw that includes a dust removal port that can be attached to a vacuum. It cuts 2-1/4 inches at 90 degrees. Unfortunately, saw does not include a rip fence, but has the attachment brackets for one. The kit includes two 18V LXT Compact 1.5Ah batteries that have an extremely fast charge time, a charger and a tool bag. The brushless motors of the three motorized components eliminate carbon brushes enabling them to run cooler and are electronically controlled to allow up to 50% longer run-time per charge. The motors efficiently use energy to match torque and RPM for the changes demands of the application They are equipped with “Star Protection Computer Controls” to protect against overloading, over-discharging and overheating. There’s a 3-year limited warranty on the tools, batteries and charger. The XDT15 ¼ inch impact driver is light weight and powerful. I was easily able to drive about 50-2 in. deck screws to mend my wooden fence without needing a battery recharge. I really liked the Assist Mode feature that disables the impact until the screws are driven. One disadvantage: the ¼ inch bits do not simply push into and “click” into the chuck like on other brands. It takes two hands to install or remove a bit. One hand to push the chuck open and the other hand to install or remove the bit. The chuck is released after the bit is installed. If the bits are rusted or corroded in any way, they will not easily be inserted into the chuck. The XPH11 ½ inch hammer drill/driver is also light weight and powerful. It easily hammer drilled ¼ inch holes into a concrete pad with little or no effort. The chuck will lock when twisted so bits can be secured or released. The cuck torque is adjustable from 1 to 20 units. The transmission speed switch is on the top of the housing. The XSH04 is a 6-1/2 inch circular saw that’s quiet and powerful. It is supplied with a general purpose 24 tooth blade suitable for most cutting tasks. The pad is fully adjustable for depth from ½ to 2-1/4 inches of cut and angle from 90 to 45 degrees. The adjustments are fully engraved into the base and there is a lock-out for each. A hex key with its own pocket is included to install or remove the blade. The blade screw has a 1/8 inch washer that must be installed between the housing and the blade for proper blade clearance. There is also a lock button for the motor shaft to prevent it from turning when removing or installing the blade and a centrifugal brake to stop the blade as soon as the on/off button is released. There’s also a battery charge indicator light on the motor housing. No LED is supplied for the base. The DML815 is a small handy 4-LED flashlight with an adjustable head. I’ve been using power tools for over 50 years and overall, I am extremely impressed with the components of this kit. They will satisfy most of the normal around the house requirements of the average DYI person, at a performance level much higher than expected.

Very nice, quality combination set. Includes Circular Saw, Hammer/Driver/Drill, Impact Driver, and Cordless Flashlight. The three tools all have a "point of work" LED light so you can see exactly where you operating the tool. Latest Brushless design on all three tools. Only the Circular Saw has battery power indicator. The graphics on the Hammer Driver Drill make it easy to set to the correct function. The battery charger is intuitive. The set comes with a nice carry bag, hooks for the hammer driver drill and a custom hook for the circular saw along with a vacuum cleaner attachment. The cordless flashlight is certainly handy and adjusts around 180 degrees. Also included are 2 (two) lithium ion 18 Volt batteries which are easily installed or removed. I would recommend this combination set. It seems to be great value and certainly a brand with a great reputation. Would make a great gift for the DIY person in your family! 3 year warranty included!!

This tool kit would be an excellent addition to any DIY or professional’s tool box. It is powerful enough to accomplish practically any job. For me it is a great item to take to job sites or situations where there is no power available. Even on sites where there is power it is really nice to be able to complete a task without having to roll out an extension cord. With 2 batteries available with quick charge time, it is a non-stop situation with no wait time waiting for charging.

Seeds Program Review
(What's this)
The Makita 18V Sub-Compact Cordless 4 Piece Combo Kit is a very versatile set. The kit that I ordered (CS401SYB) came with the following items: • XDT15 Impact Driver – This is a very compact impact driver that is very small and light weight, yet powerful. It delivers up to 1240 inch/pounds of torque, and has three settings, Hard, Soft and Assist. The Assist mode is extremely useful. It starts off in a slow rotation at first. When it begins to impact the rotation begins increasing up to the maximum speed. This is the first impact driver I have owned and it drives long screws very easily. • XPH11 Hammer Driver and Drill – This is also a compact tool but has a 1/2” chuck and a two speed transmission. It can be switched between drilling, driving screws and hammer drilling. It also works extremely well for its size. • XSH04 6 ¼” Circular Saw – This is a lightweight easy to handle saw that turns at up to 5000 rpm. It came with a 24 tooth carbide blade and will cut up to 2 ¼” depth. This is the only tool in this set that has a 3 stage LED battery gauge. It cuts extremely well. With the 1.5 Ah battery I was able to cut several smaller pieces of ¾” particle board and then approximately 50 cross cuts of a 2x4. On larger projects a higher amp/hour battery may be a nice addition. • DML815B 4-LED Flashlight – This light has an adjustable head on it and puts out 160 lumens. It uses the same 18 volt battery as the other tools. • Two – 1.5 Ah 18 volt LXT Lithium-ion Batteries with a Charger. These specific batteries do not have a level gauge built on them. • Zippered bag with shoulder strap. The tools and batteries all have a 3 year warranty. Each on has LED's that light up the work area when used. The tools are all made in China. Overall I am very satisfied with this set. Though compact, they do the work of much larger tools and perform very well. I would definitely order this set again.

Couldn’t recommend the 5.0 Ah batteries more. Although they are heavier- suck it up, it builds muscle ;). I love that I can count on the quick charge time and how long each battery lasts. Depending what tool, I can go 2-4 hours on one battery using constantly. I now have three of them and watch for deals. I couldn’t be happier.

After the $150 sticker shock for this battery subsided, I have been completely satisfied with its longevity while using it to drive deck screws. Lasted a solid 6 hours with continuous use and the charger had it ready to go again in roughly 30 minutes. Highly recommend!
