Drill bit Abraboro Morse taper HSS DIN 345 10.0 mm × 168 mm overall length × 87 mm flute length (MK1)

Abraboro HSS drill bit with Morse taper shank (MK1) manufactured to DIN 345 standards. This solid high-speed steel drill has a cutting diameter of 10.0 mm, an overall length of 168 mm and a flute/working length of 87 mm. The Morse taper shank (MK1) enables secure fitting in tailstocks or compatible Morse taper holders; the tool is intended for drilling and general machining in metals and similar materials in workshop and industrial environments.

Advantages

The Abraboro HSS material provides wear resistance and retains hardness at elevated cutting temperatures typical of metalworking. The DIN 345 geometry ensures consistent point and flute design for reliable chip evacuation and stable cutting action. The Morse taper shank (MK1) affords rigid clamping in tailstock spindles and taper adapters without requiring additional chuck adapters, reducing runout and improving concentricity.

Suitable for

• Drilling holes in steel, cast iron and non-ferrous metals
• Use in lathes with tailstock or drill presses fitted with Morse taper sleeves/adapters
• General workshop and industrial metal fabrication and maintenance tasks

Key specifications

• Cutting diameter: 10.0 mm
• Overall length: 168 mm
• Flute/working length: 87 mm
• Shank type: Morse taper MK1
• Material: High-speed steel (HSS)
• Standard: DIN 345

How to use

Mount the drill bit by inserting the Morse taper shank into a matching MK1 tailstock socket or a compatible taper holder; ensure a clean, dry connection and secure seating to minimize runout. Select appropriate spindle speed and feed for the workpiece material—use lower speeds for harder steels and higher speeds for softer alloys. Apply suitable cutting fluid to improve tool life and chip evacuation. Withdraw periodically to clear chips when drilling deeper holes; finish with a controlled feed to maintain hole quality.

Usage recommendations

Use cutting fluids appropriate for the machined material and avoid excessive feed rates that may cause chatter or premature wear. Inspect the taper shank and socket for debris before mounting. Regrind or replace the drill when wear affects diameter tolerance or cutting performance.
