Drill bit Abraboro HSS solid metal 1.2 mm set of 10 (AB00010120)

Abraboro HSS solid drill bits for metal, 1.2 mm diameter, pack of 10 are designed for precise drilling of small-diameter holes in ferrous and non-ferrous metals. Made from high-speed steel (HSS), these solid bits maintain edge hardness and cutting performance under the heat and stress typical of metalworking. The straight shank provides secure clamping in standard drill chucks and micro-drills, enabling repeatable accuracy for tasks that require fine holes.

Advantages

The high-speed steel construction offers good wear resistance and heat tolerance during continuous drilling in metal. The small 1.2 mm diameter and solid design support accurate pilot holes and detailed metalwork. A straight shank ensures compatibility with a wide range of hand-held and bench drilling tools, while the pack of ten supplies multiple replacements for workshop and production use.

Suitable for

• Precision metalworking and fabrication
• Electronics and PCB component drilling
• Model making and miniature assemblies
• General workshop use for small metal holes

Key specifications

• Material: high-speed steel (HSS)
• Diameter: 1.2 mm
• Type: solid twist drill
• Shank: straight shank for standard chucks
• Quantity: 10 pieces per pack
• Intended use: drilling in ferrous and non-ferrous metals

How to use

Select an appropriate drill speed for the workpiece material and secure the bit in the drill chuck so it is clamped firmly. Use steady feed pressure and maintain alignment perpendicular to the work surface for accurate holes. For metals, apply suitable cutting fluid or coolant to reduce heat buildup and extend bit life. After drilling small holes, clear chips frequently to avoid clogging and re-check bit condition; replace dull bits from the pack to preserve hole quality.

Usage recommendations

Use low to medium spindle speeds for small-diameter metal drilling and employ cutting lubricant when working with stainless or hardened steels. Store bits in a protective case to prevent tip damage and organize spare bits from the pack for consistent workflow in precision tasks.
