Drill Bit Set Makita P-60517 – HSS-G Metal Bits, 19 pieces

Makita P-60517 is a set of 19 HSS-G drill bits designed specifically for drilling in metal. The kit contains a range of high-speed steel ground bits with diameters suited for general metalworking tasks, maintenance and workshop use. These bits are intended for use with standard drills where accurate, clean holes in steel, iron and non-hardened alloys are required.

Advantages

The HSS-G construction provides good hardness and heat resistance for continuous drilling in metal, while the ground flute geometry ensures straight, accurate drilling and efficient chip removal. The set includes a wide range of sizes to cover common diameter requirements, reducing the need to change tools during typical maintenance or fabrication work. The uniform shank design ensures compatibility with most drill chucks and offers simple, secure mounting.

Suitable for

• Drilling holes in mild steel, sheet metal and iron
• Workshop maintenance and repair tasks
• General metal fabrication and prototyping
• Pre-drilling for bolts, rivets and fasteners

Key specifications

• Material: High-speed steel, ground (HSS-G)
• Number of pieces: 19
• Intended material: Metal (steel, iron, non-hardened alloys)
• Shank type: Straight shank for standard drill chucks
• Flute geometry: Ground for accurate drilling and chip evacuation

How to use

Select the drill bit diameter appropriate for the hole size required and insert the straight shank securely into the drill chuck. Start drilling at low speed to create a positioning point, then increase speed according to material thickness and bit diameter. Use cutting fluid for improved cooling and longer tool life when drilling thicker or tougher metals. Apply steady axial pressure, avoid side loading, and withdraw periodically to clear chips for cleaner holes and to prevent bit overheating.

Usage recommendations

For best results, use the appropriate drill speed for the selected bit diameter and metal type, and apply cutting fluid on steel and iron. Store the bits in a protective case or rack to avoid damage to the cutting edges and to keep sizes organised for quick selection during workshop tasks.
