TECHNICAL DETAILS

Carbide Drills

____________________________

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

SHOP CARBIDE DRILLS

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

Indexable Drill Bodies

____________________________

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

SHOP INDEXABLE DRILL BODIES

Applications:

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

Modular Drill Bodies

____________________________

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

SHOP MODULAR DRILL BODIES

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

Spade Drill Bodies

____________________________

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

SHOP SPADE DRILL BODIES

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
