Drills are end cutting tools used to produce holes when rapid removal of material is desired
Twist drills are generally effective in holes up to 3 tool diameters deep - peck cycles should be used for deeper holes to achieve better chip evacuation
Longer flute and overall lengths than jobbers length drills
Carbide tip high temperature brazed to hardened tool steel body
Smooth flutes for effective chip flow
Precision ground to insure concentricity of tip and body
The longer length of these drills increases their effective reach through drill bushings
