A high-speed cutter with teeth made of tungsten carbide, the hardest material next to diamonds. Use on fiberglass, wood, plastic, epoxy, rubber, laminates, particleboard and ceramic tile. Teeth made of tungsten carbide, the hardest material next to diamonds. Sharp teeth for greater material removal.

• 1/8" Shank
• 1/4" Diameter
• Use on fiberglass, wood, plastic, epoxy, rubber, laminates, particleboard and ceramic tile
• Teeth made of tungsten carbide, the hardest material next to diamonds
• Sharp teeth for greater material removal
• Fast cutting
• 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 collet 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.
