Drill bit GRAPHITE 57H132 titanium-coated cylindrical 5 mm for metal

GRAPHITE 57H132 is a cylindrical 5 mm drill bit with a titanium coating, engineered for drilling steel and a wide range of metal alloys. The solid straight shank fits standard chucks of handheld drills and drill presses, allowing stable, precise hole making. The titanium layer increases surface hardness and helps reduce friction and heat buildup during cutting, extending tool life under typical workshop, construction, and repair conditions.

Advantages

The titanium coating improves wear resistance and reduces material adhesion to the cutting edges, which supports longer service life compared to uncoated high-speed steel bits. The cylindrical shank ensures secure clamping in standard drill chucks and enables consistent concentricity for accurate holes. The 5 mm diameter provides a common size for through-holes, pilot holes, and component assembly tasks in metalworking.

Suitable for

• Drilling holes in mild and alloy steels
• Workshop and maintenance metalwork
• On-site construction and repair tasks requiring metal drilling
• Use with handheld drills and drill presses

Key specifications

• Type: cylindrical straight shank twist drill
• Material: high-speed steel body with titanium surface coating
• Diameter: 5 mm
• Intended use: drilling in steel and metal alloys
• Compatibility: standard drill chucks on handheld drills and drill presses

How to use

Secure the drill bit in the chuck ensuring correct centring and tight clamping. Select an appropriate drill speed for the metal being worked: lower speeds for harder alloys and higher speeds for softer metals, while avoiding excessive heat. Use cutting lubricant when drilling steel to reduce friction and extend bit life. Apply steady pressure and allow the bit to cut without forcing; periodically clear chips from the hole to maintain efficient cutting.

Usage recommendations

For best results, start with a pilot hole for large or deep holes, use cutting fluid for prolonged drilling in steel, and replace the bit when wear or chipping reduces cutting performance. Store the bit in a dry place to prevent corrosion of the substrate under the coating.
