Metal drill bit GEKO 23 x 155 mm, shank for metal drilling

GEKO metal drill bit 23 x 155 mm with a shank designed for metal drilling is intended for creating through-holes, pilot holes and other general metalworking tasks. The bit is made from a single solid piece of high-strength material and shaped to provide stable cutting performance in steel and a range of other metals. It is compatible with hand drills and drill presses that accept the shank size, delivering consistent hole quality for workshop and professional applications.

Advantages

The geometry and hardness of the flute and cutting edges are balanced to reduce wandering at the start of drilling and to maintain a steady feed. The solid construction and heat-resistant properties extend tool life under typical workshop conditions. The shank ensures secure clamping in standard chucks and the overall length provides reach for deeper holes while preserving rigidity for cleaner finishes.

Suitable for

• Drilling through steel plates and structural elements
• Creating pilot holes for tapping or larger hole saws
• Workshop and maintenance tasks on machinery and metal assemblies
• Use with hand-held drills and stationary drill presses

Key specifications

• Diameter: 23 mm
• Total length: 155 mm
• Material: solid high-strength metal suitable for cutting steel and other metals
• Shank type: straight shank for standard drill chucks and presses
• Intended use: through-holes and pilot holes in metalwork

How to use

Secure the drill bit firmly in the chuck before starting. Use appropriate cutting speed and feed rate for the specific metal being drilled; lower speeds are recommended for hard steels and higher speeds for softer metals. Apply steady pressure without forcing the bit; allow the tool to cut at its own rate. Use cutting fluid or lubricant to reduce heat and prolong bit life, and periodically clear chips from the hole to prevent clogging and overheating.

Usage recommendations

For best results, match drill speed and cutting fluid to the material: slower speeds and active lubrication for hardened steels, moderate speeds for mild steel and higher speeds for non-ferrous metals. Inspect the bit for wear or chipping before use and replace when cutting performance declines to maintain hole accuracy and safety.
