## Summary description

Cylindrical HSS drill bit by GRAPHITE, 8 mm diameter (model 55H029). Designed for drilling metal and other hard materials, the high-speed steel (HSS) construction provides wear resistance and maintains edge hardness at elevated temperatures. Suitable for hand drills and drill presses for metalworking tasks, repairs, and fabrication.

## Long description

GRAPHITE cylindrical HSS drill bit, 8 mm diameter (model 55H029), is a high-speed steel tool designed for drilling metals and other hard materials. The solid cylindrical shank fits standard chucks on hand drills and drill presses. Constructed from HSS, the bit retains hardness at higher temperatures and offers wear resistance under typical metalworking conditions. Its geometry is intended to provide reliable chip evacuation and consistent hole quality when used with appropriate speeds and cutting fluids.
Advantages
The HSS material ensures good heat resistance and edge retention during continuous drilling operations in steel and non-ferrous metals. The cylindrical shank design provides secure clamping and compatibility with a wide range of drilling machines. The 8 mm diameter delivers a balance between rigidity and cutting capacity for medium-sized holes, while the ground flutes promote stable cutting and predictable hole dimensions.
Suitable for
 Drilling through mild and alloy steels
 Working with non-ferrous metals such as aluminum and brass
 General metal fabrication, maintenance and repair tasks
 Use in hand drills and bench or pillar drill presses
Key specifications
 Material: High-speed steel (HSS)
 Shank type: Cylindrical
 Diameter: 8 mm
 Intended materials: Metals and other hard materials
 Typical use: Drilling with cutting fluid or coolant recommended for metalworking
How to use
Secure the drill bit in the chuck of a hand drill or drill press, ensuring concentric clamping and correct tightening. Select appropriate spindle speed according to the workpiece material—lower speeds for harder steels and higher speeds for softer, non-ferrous metals. When drilling metal, apply steady feed pressure and use cutting fluid or coolant to reduce heat and improve tool life. After drilling, retract the bit periodically to clear chips and avoid clogging the flutes.
Usage recommendations
For best results, pre-center the hole with a center punch when drilling sheet or thin materials, use appropriate cutting speeds and lubrication, and inspect the bit for wear before use to maintain hole accuracy and prolong service life.
