Drill bit Abraboro HSS cylindrical 5.2 mm, metal, set of 10 (AB00010522)

Abraboro HSS cylindrical drill bits with a 5.2 mm cutting diameter are engineered for drilling and enlarging holes in metal. This set contains ten high-speed steel bits with a straight shank that fits standard drill chucks. The geometry and material are intended to provide reliable cutting performance when working with steel and other ferrous and non-ferrous metals in workshop, maintenance and fabrication environments.

Advantages

The HSS material offers good hardness and heat resistance for general-purpose metal drilling. A straight (cylindrical) shank ensures secure clamping in a wide range of drills and chucks. Supplied as a set of ten, these drill bits provide consistent 5.2 mm hole size for repetitive tasks and reduce downtime for tool changes. The bits are suitable for both manual and machine drilling operations under recommended speeds and feed rates.

Suitable for

• Drilling and reaming 5.2 mm holes in steel and cast iron
• Working with non-ferrous metals such as aluminum, brass and copper
• Workshop maintenance, fabrication and repair tasks
• Use in hand-held drills and bench or pillar drilling machines

Key specifications

• Cutting diameter: 5.2 mm
• Material: high-speed steel (HSS)
• Shank type: straight/cylindrical
• Set quantity: 10 pieces
• Intended application: metal drilling (ferrous and non-ferrous)

How to use

Secure the required bit in the drill chuck, ensuring the straight shank is seated and tightened. Select an appropriate drilling speed and feed for the workpiece material; lower speeds are generally better for harder steels, while higher speeds can be used for softer non-ferrous metals. Use cutting fluid or lubricant when drilling steel to reduce heat build-up and prolong bit life. Start with a center punch for precise hole placement if necessary, and apply steady, even pressure while drilling. Clear chips periodically to avoid clogging the flutes.

Usage recommendations

For best performance and tool life, match drilling speed and feed to the material, use cutting fluid on steel, and avoid excessive side loads. Replace worn bits to maintain hole accuracy and reduce the risk of breakage.
