PRECISION-MAX STEP POINT 4.2MM HSS DRILL 10 PACK

Features

• 4.2 mm diameter — fits many pilot and fastener size applications.
• Step-point tip — reduces walking and improves hole start accuracy.
• Split point design — allows finer entry with less force.
• Tri-flat shank — helps prevent slipping under torque.
• M2 HSS material — a durable, general-purpose drill steel.
• Fully ground flutes — smoother chip evacuation.
• Packed in 10 pieces — ensures continuity during production runs.

Benefits

• Cleaner starts: step-point geometry and split point reduce burrs and entry damage.
• Greater consistency: all bits in the pack maintain geometry for uniform performance.
• Reduced downtime: extra bits in pack reduce reloading or tool change interruptions.
• Versatile use: suitable for metal, plastic, laminate and composite sheet drilling.

Extra Information

• Use cutting fluid when drilling steel to reduce heat, friction and wear.
• Moderate speed and feed — avoid overdriving which may reduce bit life.
• Support thin or delicate materials with backing stock to prevent exit breakout.
• Rotate use among bits to minimize differential wear within the pack.

Specifications

Safety

• Wear eye protection — chips or fragments may eject during use.
• Secure the workpiece in a jig or clamp — do not drill freehand on small parts.
• Apply even feed; avoid forcing the bit sideways.
• Manage heat — allow rest or coolant to keep bits cool and retain cutting edge.
