CARBIDE TIPPED VS. HIGH SPEED STEEL |
ADVANTAGE #1 | - Higher feeds & speeds
- Retains cutting edge at very high machining temperature (see upper right graph)
- More aggressive machining reduces cycle time
|
 |
ADVANTAGE #2 | - Exceptional wear resistance at cutting edge
- Holds size far longer (see lower right graph)
|
 |
ADVANTAGE #3 | - Far longer runs before resharpening
- Reduces machine downtime for tool changes
- Chip forming surface resists wear much better
- Cratering minimized

CARBIDE TIPPED VS. SOLID CARBIDE |
ADVANTAGE #1 | - Carbide grade selected for cutting characteristics - not compromised for structural strength
- More aggressive cutting edge geometries - shear, edge & rake angles
- Hardened tough alloy steel body provides superior structure to absorb shock loads
|
 |
ADVANTAGE #2 | - Carbide cracks stopped in steel body pocket rather than shattering the entire tool
- Reduced scrap & machine downtime as even a cracked carbide tipped tool keeps cutting
- A shattered solid carbide tool often damages the piece being machined
|
 |
ADVANTAGE #3 | - Tipped tools usually cost less than solid carbide
- Expensive carbide only used for cutting edge & chip forming surface
- Often utilize specialty carbides not available in solid round forms

CARBIDE TIPPED VS. CARBIDE INSERT |
ADVANTAGE #1 | - Initial tooling costs far lower for carbide tipped tools
|
 |
ADVANTAGE #2 | - Insert pocket interferes with chip flow
- Vibration-free brazed carbide tip permits higher feeds & speeds since inserts simply cannot be securely clamped to avoid all vibration problems
- Far better finish using carbide tipped tools
|
 |
ADVANTAGE #3 | - Inserts are impractical for many operations such as reaming and most drilling
