Drill bit Abraboro HSS 1.5 mm — high-speed steel twist drill for metal and general-purpose drilling

Abraboro HSS 1.5 mm is a high-speed steel twist drill designed for precision drilling in metal and general-purpose applications. With a 1.5 mm diameter and HSS construction, this drill bit is intended for creating small, accurate holes in thin metal sheets, components in electronic assemblies, and detailed workshop or machinery tasks. The straight-shank twist design fits standard drill chucks and is suitable for both manual hand drills and drill presses when small-diameter, high-speed steel tooling is required.

Advantages

The Abraboro HSS 1.5 mm drill bit offers high hardness and heat resistance of HSS material, which helps maintain edge geometry under elevated cutting temperatures. Its small diameter provides precise hole placement and minimal material displacement, beneficial for delicate components and tight-tolerance work. The standard twist geometry promotes efficient chip evacuation for small holes and compatibility with common drilling equipment simplifies tool changes.

Suitable for

• Drilling small-diameter holes in thin metal sheets and plates
• Creating pilot or alignment holes in electronic components and circuit boards (where appropriate for material)
• Workshop tasks requiring precision holes in mechanical parts
• Model making and small-scale fabrication
• Use in hand-held drills and drill presses for general-purpose metal drilling

Key specifications

• Material: high-speed steel (HSS)
• Type: twist drill bit with straight shank
• Diameter: 1.5 mm
• Intended use: metal and general-purpose drilling
• Compatibility: standard drill chucks (hand drills and drill presses)

How to use

Select a suitable drill speed and feed for the small 1.5 mm HSS bit and the specific metal being drilled. Secure the workpiece to prevent movement and center-punch the drilling point if necessary to improve accuracy and prevent walking. Install the drill bit in the chuck and ensure it is held straight and firmly. Use a light, steady feed pressure and apply cutting fluid or lubricant when drilling harder metals to reduce heat and extend tool life. After drilling, remove swarf and inspect the hole for correct dimensions.

Usage recommendations

For optimal performance, use moderate spindle speeds appropriate for 1.5 mm HSS tooling and the material type, avoid excessive axial force that can break small-diameter bits, and employ cutting fluid when machining steel or alloys to prolong tool life and improve hole quality.
