Drill bits set Makita D-77241 HSS-G for metal, 6 pcs — 2, 3, 4, 5, 6, 8 mm

Set of six Makita D-77241 HSS-G drill bits for metal, including sizes 2, 3, 4, 5, 6 and 8 mm, manufactured from high-speed steel (HSS-G). These bits are intended for drilling through a variety of ferrous and non-ferrous metals and are suitable for use in hand drills and drill presses. The compact set covers common small-to-medium hole diameters used in workshop tasks, maintenance and light fabrication.

Advantages

HSS-G construction offers good hardness and heat resistance for extended cutting life during metal drilling. The set provides a practical range of commonly used diameters, reducing the need to switch tools for routine metalworking tasks. Machined flutes ensure efficient chip evacuation, and the straight shank design fits standard chucks for secure mounting in both portable and stationary drills.

Suitable for

• General metal fabrication and sheet metal work
• Maintenance and repair tasks involving steel, aluminium and other metals
• Workshop projects and do-it-yourself (DIY) home repairs
• Drilling with hand drills and drill presses

Key specifications

• Material: high-speed steel (HSS-G) for cutting and heat resistance
• Set contents: six drill bits — 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 8 mm
• Shank type: straight shank compatible with standard chucks
• Intended use: metal drilling (ferrous and non-ferrous materials)
• Typical mounting: suitable for hand drills and drill presses

How to use

Select the appropriate diameter for the hole required and secure the drill bit in the chuck, ensuring the bit is straight and tightened. Use a center punch for accurate start on sheet materials if needed. For metal drilling, apply steady pressure and maintain a moderate spindle speed suitable for the material and bit size to avoid overheating. Use cutting fluid or lubricant on harder metals to reduce heat and improve tool life. After drilling, clear chips from the work area and inspect the hole for burrs that may require deburring.

Usage recommendations

For best results when drilling metal, start with a pilot hole for larger diameters, use appropriate cutting lubricant on harder alloys, and select speeds that balance cutting efficiency with heat control. Store bits in a dry place to prevent corrosion and check for wear before critical tasks.
