PRECISION-MAX STEP POINT 4.0MM HSS DRIL 10 PACK

Features

• 4.0 mm diameter — common size for pilot holes and fasteners.
• Step-point geometry — helps ensure accurate, clean entry even without pre-punching.
• High Speed Steel (HSS) construction — durable, general-purpose tool material.
• 10-pack format — maintain workflow with backup bits available.
• Straight shank — compatible with standard 3-jaw chucks on drills and machines.
• Typical UPC / identification for this product (if known) can be added here.

Benefits

• Reliable start: step-point tip reduces wandering, especially on smooth or coated surfaces.
• Consistent output: identical bits allow rotation and predictable wear profiles.
• Reduced downtime: backup bits help avoid pauses in production.
• Versatile application: suits metal, plastic, laminated composites and thin skin materials.

Extra Information

• Use cutting fluid or lubrication when drilling metals to increase bit life and surface quality.
• Start at moderate RPM and feed; avoid excessive pressure that deflects bits.
• For thin sheet, back material with scrap to prevent exit breakout.
• Rotate through bits in the pack to balance usage and wear over time.

Specifications

Safety

• Wear eye protection — metal chips or fragments may eject.
• Secure the workpiece firmly before drilling.
• Apply steady feed pressure; avoid forcing the bit sideways.
• Use coolant, breaks or lower speeds to control heat and reduce wear.
