Drill bit set Abraboro HSS cylindrical for metal 9 mm, 10 pcs (AB00010900)

Abraboro HSS cylindrical drill bit set for metal, 9 mm diameter, 10 pieces is a set of high-speed steel twist drills designed for drilling through-holes and general metalworking. The bits are intended for use in handheld drills and drill presses, providing consistent 9 mm holes in steel and a variety of other metals used in fabrication, repair and maintenance tasks.

Advantages

High-speed steel construction ensures good wear resistance and heat tolerance during medium-speed drilling in metals. The cylindrical shank design allows secure clamping in standard drill chucks. Sold as a 10-piece set, the selection supports repeated operations and replacement of worn tools without interruption to work. The twist-flute geometry provides efficient chip evacuation for typical metal drilling applications.

Suitable for

• Drilling 9 mm through-holes in steel components
• General metal fabrication and repair tasks
• Use with handheld electric drills and drill presses
• Maintenance and installation jobs requiring consistent 9 mm holes

Key specifications

• Material: high-speed steel (HSS)
• Diameter: 9 mm
• Shank type: cylindrical
• Quantity: 10 pieces per set
• Intended application: drilling through-holes in metal

How to use

Select a suitable drill speed for the metal you are working with and secure the workpiece. Clamp the 9 mm cylindrical shank firmly in the drill chuck. Begin drilling at a controlled feed rate, applying steady pressure while allowing the bit to cut. Withdraw periodically to clear chips if drilling deep holes. Use cutting fluid or coolant where appropriate to reduce heat and prolong tool life.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves, choose cutting speed and coolant according to the metal grade, and replace bits when wear or chipping affects hole quality.
