Drill bit GEKO HSS cobalt for metal 1.5 mm, model G37015

GEKO HSS cobalt drill bit for metal, 1.5 mm diameter, model G37015 is a precision cutting tool engineered for drilling small-diameter holes in steel, stainless steel and other hard metals. Made from high-speed steel with a cobalt alloy, this drill bit offers enhanced heat resistance and improved wear performance compared with standard HSS bits. Its compact 1.5 mm size is intended for applications requiring accurate, clean boreholes using handheld drills or drill presses.

Advantages

The cobalt-enriched HSS construction increases hardness at elevated temperatures, allowing longer cutting life and better performance when penetrating tougher materials. The small 1.5 mm diameter provides precise hole placement and minimal material removal for fine work. The bit is suited to both handheld and machine drilling, delivering consistent results when used at appropriate speeds and with correct cooling/lubrication.

Suitable for

• Drilling precision holes in steel and stainless steel
• Small-diameter metalworking tasks in workshops and production
• Use with handheld electric drills and drill presses
• Making pilot holes for fasteners and assembly in thin metal parts

Key specifications

• Material: high-speed steel with cobalt alloy
• Diameter: 1.5 mm
• Intended use: metal drilling (including stainless steel and other hard metals)
• Suitable tools: handheld drills and drill presses
• Tip style: standard twist drill geometry for metal

How to use

Select an appropriate drilling speed for small-diameter cobalt HSS bits — typically higher speeds for softer steels and lower speeds for stainless and harder alloys — and secure the workpiece to prevent movement. Use a center punch to locate the hole, start drilling with light pressure to establish the cut, and maintain steady feed without excessive lateral force. Apply cutting fluid or lubricant as needed to reduce heat and extend bit life; withdraw the bit periodically to clear chips when drilling deeper holes.

Usage recommendations

For best results, use a firm clamping method, proper cutting lubricant, and a steady drilling speed appropriate for the material. Avoid side loading and rapid overheating; replace the bit when wear or chipping reduces hole quality.
