Drill bit Abraboro HSS cylindrical 5.2 mm, set of 10 (AB00010520)

Abraboro HSS cylindrical 5.2 mm drill bit set contains ten identical high-speed steel bits designed for general workshop and light industrial drilling. Each bit has a 5.2 mm cutting diameter and a straight cylindrical shank that fits standard chucks and holders. The HSS material provides wear resistance and maintains cutting edge stability when drilling common metals and many general-purpose materials, making the set suitable for repetitive tasks where consistent hole size is required.

Advantages

The HSS construction offers a balance of hardness and toughness for reliable drilling in steel, non-ferrous metals and similar materials. Cylindrical shanks ensure compatibility with a wide range of handheld and bench-mounted chucks. Supplied as a set of ten identical bits, it reduces downtime by providing immediate replacements and supports batch drilling with uniform hole diameter. The consistent geometry and manufacturing quality help deliver repeatable hole accuracy and stable performance under standard workshop conditions.

Suitable for

• Drilling holes in mild and medium-hard steels
• Working with aluminium and other non-ferrous metals
• Routine maintenance and fabrication tasks
• Batch drilling where multiple identical holes are required
• General-purpose workshop and light industrial use

Key specifications

• Cutting diameter: 5.2 mm
• Material: High-speed steel (HSS)
• Shank type: Cylindrical (straight) shank for standard chucks
• Quantity: Set of 10 identical drill bits
• Intended use: Metalworking and general-purpose drilling

How to use

Install a 5.2 mm HSS bit into a compatible chuck and tighten securely before starting the drill. Select an appropriate spindle speed and feed rate for the work material—lower speeds for harder steels and higher speeds for softer metals like aluminium. Use cutting lubricant when drilling steel to reduce heat and extend tool life. Withdraw the bit periodically to clear chips and prevent clogging, and inspect the cutting edges for wear, replacing bits from the set as needed to maintain hole quality.

Usage recommendations

For best results, match cutting speed and lubrication to the material being drilled: use cutting oil for ferrous metals and moderate speeds for stainless or hardened steels. Use a center punch to locate holes accurately and a pilot drill when drilling larger assemblies to improve alignment. Store the bits dry and protected to prevent corrosion and maintain performance.
