Makita D-06339 HSS Drill Bit for Metal 4 x 75mm

Diameter: 4 mm; Length: 75 mm; Material: High-Speed Steel (HSS); Pack size: 1 drill bit; Coating: heat-resistant coating to help maintain sharpness during prolonged use; Compatibility: designed to fit most drills with a standard chuck.

Ideal for drilling through various metals such as mild steel, stainless steel, aluminum, and other common metalwork materials. For hardened or very thick metals, ensure the bit remains sharp and use appropriate cutting fluid and controlled speeds.

Use slower to mid-range speeds suitable for metal drilling and apply steady feed pressure. Keep the bit cool with cutting oil or appropriate coolant, and avoid forcing the bit; let the bit cut at its own pace to minimize heat and wear.

Insert the 4 mm bit straight into a chuck and tighten securely. Ensure there is no wobble, and that the bit is running true before starting. If your drill uses a keyless chuck, hand-tighten and verify it’s secure.

Wear eye protection and gloves, clamp the workpiece securely, and keep hands away from the rotating bit. Use cutting fluid or coolant to reduce heat, avoid overheating, and stop drilling if the bit becomes dull or binding.

Keep the bit clean and dry, remove metal shavings after use, and store in a protective case to prevent nicks. Regularly inspect the cutting edges for wear and re-sharpen or replace as needed to maintain performance.

Ideal for creating small-diameter holes in metalwork projects, automotive repairs, cabinetry, metal fabrication, and DIY metal drilling tasks where precise 4 mm holes are required and a longer 75 mm reach is advantageous.
