Features

Type 190-AG
Magnum Super Premium - 135° Split Point - Wire

WHY CHOOSE MAGNUM?

SUBSTANTIALLY LONGER CUTTING LIFE
The nitro-carburized flute has an increased Rockwell hardness.

CUTS HARDER MATERIALS
The flatter point takes a smaller chip. More torque is directed to a smaller area.
This allows drilling into materials with hardness of over 30 on the Rockwell "C" scale.

STOPS DRILL WALKING
The split point design gives accurate starting without the use of a center punch.

HOLDS TIGHTER HOLE SIZE
The split point design is self centering. This limits the normal oversize drilling characteristics.

OUTSTANDING QUALITY APPEARANCE
The rich amber gold color sets it apart from commodity cutting tools.

RUNS COOLER, USES LESS TORQUE
135° point takes a smaller chip resulting in less heat. Friction is reduced by amber gold
surface treatment.

STOPS CHUCK SLIPPAGE
Flats on drill shanks allow easy positive chuck grip.

Special Hi-Molybdenum tool steel. 135° split point for fast penetration and accurate starting without a center punch. precision ground point, flutes, body, clearance and drill diameter for the ultimate in accuracy and performance. Body and clearance are gold surface treated for maximum lubricity. Drills are heat treated at 2185°f and then nitro-carburized finished at 950°f to be measurably harder than high-speed steel. Space age nitro-caburized steel withstands substantially higher drilling temperatures while maintaining sharpness. Recommended for use in work hardening grades of stainless steel and other hard metal drilling applications. Sizes smaller than #52 have non-split points.
