Drill bit set Abraboro HSS cylindrical 3.2 mm, 10 pcs (AB44003200)

Abraboro HSS cylindrical 3.2 mm drill bit set contains ten identical high-speed steel bits designed for drilling metal. Each bit has a 3.2 mm working diameter and a cylindrical shank suitable for use in drill chucks and drill presses. The HSS material provides hardness and heat resistance needed for cutting ferrous and many non-ferrous metals, making the set appropriate for workshop, repair and light manufacturing applications where repeatable hole diameter and wear resistance are required.

Advantages

The high-speed steel construction ensures good edge retention and performance at elevated cutting temperatures. Cylindrical shanks allow straightforward mounting in standard chucks and minimize the need for adapter tools. Supplied as a pack of ten identical bits, the set offers consistent hole sizes for repetitive tasks and a ready supply of replacements to reduce downtime. The 3.2 mm diameter is a common size for mechanical assemblies, electronics enclosures and light fabrication.

Suitable for

• Drilling steel and other ferrous metals
• Drilling aluminium, brass and other non-ferrous metals
• Workshop maintenance and repair tasks
• Prototype work and small-batch manufacturing
• General-purpose drilling with hand drills and drill presses

Key specifications

• Material: high-speed steel (HSS)
• Flute type: conventional twist drill geometry
• Shank type: cylindrical
• Diameter: 3.2 mm
• Quantity: 10 pieces

How to use

Select an appropriate drill speed and coolant or cutting lubricant for the metal being drilled. Secure the workpiece and mount the cylindrical shank in a suitable chuck or drill press arbor. Begin drilling with light pressure to establish the hole, then apply steady feed while maintaining alignment. Periodically withdraw the bit to clear chips and, when machining harder materials or prolonged runs, use cutting fluid to reduce heat and wear. Replace the bit when wear or chipping affects hole quality.

Usage recommendations

If drilling stainless steel or other hard alloys, reduce spindle speed and use appropriate cutting lubricant to extend bit life. For precise diameter holes, use the set in a drill press with proper clamping and alignment. Store the bits dry and protected to avoid corrosion and preserve cutting edges.
