Drill bit Makita 6 mm HSS B-42466 for metal and general drilling

Straight shank 6 mm HSS drill bit from Makita designed for clean, accurate holes in metal and similar general-purpose materials. The high-speed steel construction provides a balance of hardness and toughness suitable for drilling mild steel, non-ferrous metals and common workshop materials. Its 6 mm diameter and straight shank make it compatible with most handheld and bench drills, offering stable rotation and straightforward bit changes.

Advantages

The HSS material offers good wear resistance and maintains cutting sharpness under typical drilling conditions. The straight shank ensures secure clamping in standard chucks and reduces wobble during operation. Precision-ground flutes promote efficient chip removal and help maintain hole accuracy. The bit is suitable for repeated use in workshop and construction settings where consistent performance is required.

Suitable for

• Drilling holes in mild and low-alloy steel
• Working with non-ferrous metals such as aluminum and brass
• General-purpose drilling in maintenance and repair tasks
• Use with handheld drills and drill presses

Key specifications

• Diameter: 6 mm
• Material: High-speed steel (HSS)
• Shank type: Straight shank
• Suitable materials: Metal and general-purpose workshop materials
• Intended use: Manual and machine drilling

How to use

Select an appropriate drill speed for the material being drilled and secure the workpiece to prevent movement. Insert the straight shank into the drill chuck and tighten firmly. Start drilling with light pressure to establish the hole, then increase to steady pressure while allowing the drill bit to cut without forcing. Periodically withdraw the bit to clear chips and reduce heat buildup; for thicker or harder metals, use cutting fluid or lubrication to extend tool life and improve hole quality.

Usage recommendations

For best results when drilling metal, use moderate speed and appropriate cutting lubricant. Keep the bit cool by pecking (periodically withdrawing) on deep holes, and replace the bit if wear or burrs appear to maintain hole accuracy.
