9904 Dremel Tungsten Carbide Cutter
- Use on Hardened steel, fired ceramics and other hard materials
- 1/8″ Maximum cutting head
- 1/8″ Shank
- Do not use for drilling or enlarging holes less than twice the diameter of the cutter to avoid carbide surface catching side of hole and breaking
- For best results insert bit in tool and back out slightly before tightening down to provide plenty of shank for the collect or chuck to hold 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
