Drill bit GEKO G39600 HSS TiN for metal 10.0 mm DIN 338

Solid high-speed steel (HSS) drill bit GEKO G39600 with titanium nitride (TiN) coating, 10.0 mm diameter, manufactured to DIN 338 specification for metal drilling. The straight-shank, two-flute geometry delivers stable drilling performance in a variety of ferrous and non-ferrous metals. The TiN coating reduces friction and increases surface hardness, helping to extend tool life and maintain cutting efficiency in workshop and industrial environments. Suitable for use in hand-held and stationary drills where precise, repeatable metal holes are required.

Advantages

The TiN coating improves wear resistance and reduces heat buildup during drilling, allowing longer continuous operation compared with uncoated HSS bits. Manufactured to DIN 338 dimensions, the drill bit provides consistent fitment in standard chucks and predictable drilling depth. The HSS core provides toughness against chipping in intermittent drilling, while the 10.0 mm diameter meets common hole size requirements for mechanical and assembly tasks.

Suitable for

• Drilling holes in mild steel, stainless steel, aluminum and other non-hardened metals
• Workshop and industrial drilling tasks using hand-held or bench drills
• Preparation of holes for bolts, rivets, and mechanical fasteners

Key specifications

• Material: high-speed steel (HSS)
• Coating: titanium nitride (TiN)
• Diameter: 10.0 mm
• Shank type: straight
• Flute: two-flute design
• Standard: DIN 338 (twist drill geometry and dimensions)
• Intended use: metal drilling

How to use

Secure the workpiece using clamps or a vise to prevent movement. Fit the drill bit into the chuck of a hand-held or stationary drill and tighten securely. Use an appropriate spindle speed for a 10.0 mm HSS bit and the specific metal being drilled; lower speeds are recommended for harder steels, higher speeds for softer metals such as aluminum. Apply steady, moderate feed pressure and use cutting fluid or lubricant when drilling stainless steel or other tough alloys to reduce heat and improve chip evacuation. Clear chips frequently to maintain cutting efficiency.

Usage recommendations

For best results, select drill speeds and feed rates appropriate to the workpiece material and use cutting fluid for prolonged tool life. Inspect the bit for wear or chipping before use, and regrind to correct geometry if necessary according to standard twist-drill practices.
