Turn your Dremel rotary tool into a powerful high-speed cutter. Create stylish designs on wood, fiberglass, ceramics, jewelry, soft metals and more. Our powerful, simple-to-use engraving cutters make it easy to express your creativity. Two cutters per pack. Dermal 115-5/16 in. High speed cutter is ideal for shaping, hollowing, grooving, slotting, inlaying and making tapered holes. For best results, insert the accessory bit all the way into the tool and then back it out slightly before tightening down. This provides plenty of shank for the collect or chuck to hold onto the bit.
  • Secure objects to a stable surface while working
  • Use the sides of the cutter (rather than the tip) for effective cutting the tip cuts poorly and can break under pressure
  • Use higher speeds for hard woods, slower speeds for metals and very slow speeds for plastics (to avoid melting at the point of contact)
  • If chattering occurs, increase speed
  • Great for cutting on curved surfaces
  • Turns Dremel rotary tools into high-speed cutting tools

Cuts perfectly!
[This review was collected as part of a promotion.] I bought this to cut recess lockset in the door. The door had a wood core and it cut through like butter.

    You’re going to want this
    [This review was collected as part of a promotion.] You definitely want this bit in your arsenal if you carve anything of a smaller nature or have fine details in your work. This bit is a monster when it comes to removing stock in small areas and perfecting the overall appearance of a project. Like many bits in its category, the blades retain a good edge, but do wear down and require maintenance. The task of correcting this issue can be tedious, and is usually accompanied with a need to clear the cutter channels as well. Personally, I hold Dremel to a higher standard and tend to be a bit hard on the tool and it’s bits, resulting in overheating it at which point it can become loose, slip from the colander, and sometimes act as a projectile. Overall, I recommend this for all carving work, as well as safety glasses and the practice of not pushing your tools to extremes.

        new style #115 cutter
        New style cutter (cutting edge straight up & down) does not work well at all for precise depth cuts in wood {{ ie. hinges , strike plates}. If depth is already cut then this one works for widening the area but not to get a level depth cut. The old style #115 had cutting edge in a spiral, I had used that style for years and never had a problem doing both cuts. Recommend old style YES Recommend new style NO!!!!!!!!!!!!!
