## Summary description

GRAPHITE drill bit model 57H136 is a 5.5 mm diameter metal drill with a titanium coating and a cylindrical (walcowy) shank. Designed for drilling metals, it offers increased surface hardness and wear resistance from the titanium layer. Suitable for handheld drills and drill presses for metalworking tasks such as creating holes in steel, iron and non-ferrous alloys.

## Long description

GRAPHITE 57H136 is a 5.5 mm metal drill bit with a cylindrical shank and a titanium coating, intended for drilling holes in steel, iron and non-ferrous alloys. The tool is made for general metalworking tasks with handheld drills and drill presses. The titanium layer increases surface hardness and wear resistance to extend cutting life under typical workshop conditions.
Advantages
The titanium-coated working edges provide improved wear resistance and maintain cutting performance during prolonged use. The cylindrical shank fits standard three-jaw chucks and allows quick mounting in handheld drills and bench drill presses. The 5.5 mm diameter offers a common size for through-holes and pilot holes in metal fabrication. Overall design balances cutting efficiency and tool life for routine metal drilling tasks.
Suitable for
Drilling through mild and medium-hard steel sheets
Creating holes in cast iron and wrought iron components
Working with non-ferrous alloys such as aluminium and brass
General maintenance and repair tasks using handheld drills or drill presses
Key specifications
Drill diameter: 5.5 mm
Shank type: cylindrical shank compatible with standard chucks
Coating: titanium surface layer for increased hardness
Intended material: steel, iron and non-ferrous alloys
Tool type: twist drill bit for metal
How to use
Secure the drill bit in the chuck so that the shank is held straight and firmly. When drilling metal, mark the hole position and, if necessary, use a center punch to prevent walking. Use moderate feed pressure and a suitable cutting speed for the material being drilled; reduce speed for harder steels and increase speed for softer non-ferrous metals. Apply cutting fluid or lubricant to the drill tip to reduce heat and extend tool life. Withdraw the bit periodically to clear chips when drilling deeper holes.
Usage recommendations
For best results, select a cutting speed appropriate to the workpiece material, use steady clamp-fixturing, and apply cutting fluid during drilling. Replace the bit when wear increases or when chipping affects hole accuracy.
