Precision-max Step Point 4.0mm Hss Drill Ind. 1pce

Extra Information

• Apply cutting fluid when drilling ferrous metals to extend bit life and improve surface finish.
• Back up thin sheet materials with scrap to reduce exit breakout.
• Use steady feed rates and avoid sudden force that can deviate or break the bit.

Features

• 4.0 mm diameter — suitable for larger pilot holes and small fasteners.
• Step-point tip — self-centering design for reduced wander and clean entries.
• HSS construction — strikes balance between toughness and wear resistance.
• Straight shank — compatible with standard 3-jaw chucks.
• Single-bit packaging — ideal for replacements or occasional use.

Benefits

• Cleaner starts: step-point geometry helps produce balanced, burr-minimized entries.
• Improved control: self-centering tip reduces need for pilot punches.
• Versatility: effective in metals, plastics, laminates and composite materials.
• Efficiency: direct start reduces setup errors, especially in tight or delicate assemblies.

Safety

• Wear eye protection — chips, shards, or swarf may eject during drilling.
• Secure your workpiece firmly; never hold by hand when drilling.
• Do not force the tool; apply smooth, consistent feed pressure.
• Manage tool speed, cooling and breaks to avoid overheating the bit or workpiece.
