Carbide Cutting Tools: Tip Styles
Plug Cap or Valve Seat Flat bottom tip
✓ Maximum abrasion resistance ✓ Most common tip used
✓ Maximum toughness
✓ Medium to hard conditions ✓ 90% of the time
✓ toughest conditions – hard rock
✓ Body protection & rely on braze ✓ All types of material other than concrete
✓ Excessive impact areas joint strength to hold tip to steel ✓ Good abrasion resistance
✓ Physical lock between steel and carbide body
✓ Some impact resistance
✓ Ideal for excessive impact ✓ Helps to divert material away from
steel body, reducing steel wash
✓ Areas with uninterrupted cuts
✓ Will withstand high impact
✓ Most expensive Price Range
✓ Medium Price Range ✓ Economical Price Range

Carbide Cutting Tools: Troubleshooting
The three categories of tool failure:
• Abrasive Wear
• Heat Failure
• Mechanical Failure
➢ Each contributes to less than optimal
tool performance
➢ Wear and deterioration can be
observed through cracking, crater
wear, chipping, deformation or fracture
