ADDISON HSS Parallel Shank Twist Drill (Long)
Features
The ADDISON HSS Parallel Shank Twist Drill (Long) is a straight-shank, extra-length twist drill for jobs that need extra reach beyond standard jobber-length drills. Made from high-speed steel, it keeps a durable cutting edge across mild steel, cast iron, and general fabrication materials, and the parallel (straight) shank fits standard three-jaw drill chucks on pillar drills, hand drills, and machining centres without adapters.
How to Use
Clamp the shank securely in a drill chuck, centre-punch the work to prevent walking, and drill at moderate speed with steady, even feed. Because the extra length increases the risk of flex and wander, back the speed off compared to a standard-length drill of the same diameter and use a pilot hole for improved accuracy. Apply cutting fluid and withdraw periodically to clear chips on deeper holes.
