Drill bit Abraboro HSS-Co DIN 338 cobalt 8.0 mm AB00010802

Abraboro HSS-Co DIN 338 cobalt drill bit, 8.0 mm diameter, is made from high-speed steel alloyed with cobalt to provide improved heat resistance and longer tool life when drilling metals and harder materials. The bit follows DIN 338 geometry for straightforward, accurate drilling and is suitable for use in hand-held drills and drill presses in both workshop and industrial environments. This 8.0 mm drill delivers consistent hole quality and is intended for general-purpose metalworking where increased wear resistance is required.

Advantages

The HSS-Co material increases red-hardness and maintains cutting performance at higher temperatures compared with standard HSS bits. DIN 338 geometry ensures stable centring and efficient chip evacuation for cleaner holes and reduced walking on the material surface. The 8.0 mm diameter offers a common size for through-holes, pilot holes and fastening applications, while the robust construction improves durability under continuous or intermittent drilling loads.

Suitable for

• Drilling steel and alloyed steels
• Drilling stainless steel and other harder metals
• Workshop and maintenance drill press operations
• Hand-held drilling where precise 8.0 mm holes are required

Key specifications

• Material: high-speed steel with cobalt alloy (HSS-Co)
• Geometry: DIN 338 standard twist drill profile
• Diameter: 8.0 mm
• Primary use: metalworking and harder material drilling
• Compatibility: suitable for hand drills and drill presses

How to use

Select appropriate cutting speed and feed for the workpiece material and secure the workpiece to prevent movement. Use cutting fluid or lubricant when drilling metals to reduce heat and improve chip evacuation. Start drilling at low speed to establish a centre and then proceed at recommended speeds for HSS-Co tools. Clear chips periodically during deep holes to avoid clogging and overheating. After use, clean the drill bit and store it in a dry place to prevent corrosion.

Usage recommendations

For best results with the Abraboro HSS-Co 8.0 mm drill bit, use moderate cutting speeds for stainless steels and higher speeds for mild steels, always applying cutting fluid for heat control. Match drill speed to material thickness and rigidity of the setup; reduce feed and speed when starting thin or delicate materials to avoid breakage.
