Precision-max Step Point 4.5mm Hss Drill 10 Pack

Features

• 4.5 mm diameter — fits common fastener pilot hole size.
• Step-point tip — guides the drill to reduce wandering and improve entry alignment.
• Split point design — helps with precise starts and cleaner edges.
• Straight shank — works with standard 3-jaw chucks.
• M2 HSS material — durable construction for general workshop tasks.
• Fully ground flutes — enhance chip removal and reduce heat build-up.
• Pack of 10 bits — keeps work going with spares in hand.

Benefits

• Reliable starts: Step-point and split point provide better centering and less walking.
• Better consistency: All bits in pack maintain geometry for uniform hole quality.
• Reduced downtime: Having backup bits ensures workflow continuity.
• Versatile: Suitable for metals, plastics, laminates, and thin skin materials.

Extra Information

• Use cutting fluid when drilling metals to minimize friction, extend bit life, and improve finish.
• Begin with moderate RPM and feed rates — avoid forcing the bit.
• Support thin materials with backing to prevent exit burr or delamination.
• Alternate uses among bits in the pack to balance wear and maintain peak geometry.

Specifications

Safety

• Wear eye protection — chips and fragments may eject during drilling.
• Secure the material firmly — never drill freehand on small parts.
• Use consistent feed; avoid forcing the bit sideways.
• Monitor bit temperature; pause or cool if heat builds excessively.
