Drill bit set Abraboro HSS cylindrical 7.6 mm, 10 pcs

Abraboro HSS cylindrical 7.6 mm drill bit set contains ten identical high-speed steel bits with cylindrical shanks. The set is designed for reliable, repeatable drilling in metal and other general-purpose materials. Compact and uniform, the ten-piece collection ensures consistent hole diameter and straightforward replacement in production, workshop or home environments. The cylindrical shank format is compatible with standard chucks that accept straight shanks, offering straightforward mounting and stable rotation during operation.

Advantages

High-speed steel construction provides good wear resistance and heat tolerance for common drilling tasks in metal and mixed materials. Having ten identical 7.6 mm bits simplifies inventory and reduces downtime from frequent tool changes. The cylindrical shanks allow compatibility with a wide range of chucks and drill presses, while the uniform diameter ensures consistent hole size across multiple operations. The compact set is easy to store and transport, suitable for both intermittent and continuous use.

Suitable for

• Drilling holes in mild steel, sheet metal and non-ferrous metals
• Production runs requiring consistent 7.6 mm holes
• Workshop maintenance and repair tasks
• Home DIY projects involving metal, wood or plastics where HSS bits are appropriate

Key specifications

• Bit material: high-speed steel (HSS)
• Shank type: cylindrical (straight) shank
• Diameter: 7.6 mm
• Quantity: 10 pieces
• Typical applications: metalworking and general-purpose drilling

How to use

Secure the selected 7.6 mm HSS bit in a compatible chuck and verify it is tightened concentrically. Select appropriate speed and feed for the material being drilled; use lower speeds and steady pressure for harder metals. Apply cutting fluid when drilling steel to reduce heat and prolong bit life. Drill using steady, even pressure and withdraw periodically to clear chips if drilling deep holes. After use, clean chips and residue from the bit and store the set in a dry place to prevent corrosion.

Usage recommendations

For best results when drilling metals, use a suitable cutting fluid, start with a pilot hole if precise positioning is required, and avoid excessive feed rates that may cause bit breakage. Inspect bits for wear or dulling and replace individual items from the set as needed to maintain consistent hole quality.
