Spade Drill Bodies and Inserts
Spade drills feature a tool steel body with through-tool coolant and inserts that are secured to the tool body using screws. The straight shank diameter with a flat allows easy mounting in mill or lathe tool holders.
Benefits:
- High penetration rates and lower chip friction
- Available in larger diameters than solid drills
- Inserts can be changed without removing the tool from the holder
- Use the same drill body for different materials and sizes by changing inserts
- Drill bodies available in straight flute and spiral flute.
Features:
- High wear resistance and reduced material adhesion
- High cutting speeds and feeds
- Better hole quality over conventional spade drills
- Stable torque
- Self-centering
- Long tool life
- Smooth cutting
- Breaks chips
- Low thrust
- AlCrN coating
Insert Chip Breaker, Grade and Coating
Chip breakers and Insert grades are combined based on your selected workpiece material.
- ST chip breaker with CS carbide grade for all steels,
- Cl chip breaker with C3 carbide grade specifically for cast iron
- SS chip breaker primarily for stainless steel. Due to the 'general purpose' C2 carbide grade makes this insert also suitable for cast iron, nonferrous and high temp alloys

| C3 | (K10) | Carbide substrate with greater wear resistance specifically for cast iron |
| T15 | - | High strength cobalt subtract, suitable for general purpose machining; primary workpiece of steel |
Insert Coating
Insert Coating AlCrN
All spade drill inserts are coated with Aluminum Chromium Nitride (AICrN) to provide a thin sturdy layer that is resistant to high temps that occur when drilling. AICrN also provides excellent wear resistance and reduces chipping and breaking.
Insert Coating Hardslick
Multi-layer coating with TiAIN/WC/C structure. Providing excellent wear resistance while also offering goof lubricity properties.
Insert Coating TiAIN
High-performance coating which offer heat resistance, iproves tool life. Excellent for general purpose machining.
