Tork Craft Precision-Max Step Point 4.0Mm Hss Drill Ind. 1Pce

Description

Tork Craft Precision-Max Step Point Drill — 4.0 mm HSS (1 Piece)

Engineered for accurate holes and reliable starts, this 4.0 mm high-speed steel (HSS) step-point bit features self-centering geometry to reduce walking. Ideal for mild steel, aluminium, plastics, and thin sheet materials where precision entry is key.

Specifications

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.

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.

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.
