Holemaking

Features:

• Faster cutting rates and longer tool life
• Better positional and dimensional accuracy
• Better surface finishes
• Shorter cycle times
• Tighter tolerances and improved part quality
•  High initial cost, but lower cost per hole

Applications:

• Steel, stainless, cast iron, aluminum, and high-temp alloys
• Small- to medium-size hole diameter
• Tighter tolerance demands
• High material removal rates
• High feedrates

Features:

• High penetration rates and lower chip friction
• Less accurate than solid carbide
• Higher initial cost, but lower long-term costs
• Available in larger diameters than solid drills
• Inserts can be changed without removing the tool from the holder

Applications:

• Medium- and large-diameter holes
• Medium tolerance demands
• Blind holes requiring a “flat” bottom
• Plunge drilling operations

Features:

• Cutting performance similar to solid carbide drills
• No regrinding costs; simply replace the drill head
• Drill heads are easily changed without removing the tool from the holder
• Drill heads may be used on other drill bodies with the same seat size

Applications:

• High-performance drilling of medium-diameter holes
• High-speed drilling in steel, cast iron, and stainless 
• Deep-hole drilling (up to 5x diameter)
• Universal geometry for steel, cast iron, and stainless
• Low cutting forces and excellent self-centering capability

Features:

• High wear resistance and reduced material adhesion
• High cutting speeds and feeds
• Better hole quality over conventional spade drills 
• Use the same drill body for different materials and sizes by changing inserts
• Straight and spiral flute
• Split point for self-centering

Applications:

• Steel, stainless, cast iron, aluminum, and high-temp alloys
• Medium and large diameter holes
• Deep hole drilling (up to 8x diameter)
• Low cutting forces and excellent self-centering capability
