Drill bit for metal Abraboro HSS cylindrical 4.8 mm 10 pcs AB00010481

Abraboro HSS cylindrical drill bits for metal, diameter 4.8 mm, pack of 10 are designed for routine metalworking tasks in workshops and maintenance environments. Made from high-speed steel (HSS), these drill bits provide reliable hardness and heat resistance for drilling steel and non-ferrous metals. Their cylindrical (straight) shank fits standard chucks on hand drills and drill presses, allowing straightforward mounting and stable rotation for through-holes and general drilling operations.

Advantages

These HSS drill bits combine material strength and dimensional consistency to deliver accurate holes with good edge life under normal drilling conditions. The straight shank design enables use with a wide range of standard chucks and reduces the need for adapter accessories. Supplied as a set of 10, the pack ensures convenient replacement and continuity of work without frequent reordering.

Suitable for

• Drilling through mild and hardened steels (within HSS capability)
• Working with non-ferrous metals such as aluminum and brass
• General workshop maintenance and repair tasks
• Use in hand-held drills and drill presses for prototype and production drilling

Key specifications

• Material: high-speed steel (HSS)
• Diameter: 4.8 mm
• Shank type: cylindrical (straight) shank for standard chucks
• Pack quantity: 10 pieces
• Intended use: metal drilling (steel and non-ferrous metals)

How to use

Select the 4.8 mm HSS bit from the pack and secure it in the drill chuck, ensuring proper tightening to avoid runout. Use appropriate cutting speed and feed rate for the metal being drilled; reduce speed and apply steady pressure when working with harder steels. Apply cutting fluid or lubricant when drilling steel to extend tool life and improve chip evacuation. For through-holes, back the bit out periodically to clear chips and avoid clogging.

Usage recommendations

Wear appropriate personal protective equipment, including safety glasses and gloves. Match drill speed and lubrication to the specific metal type to maximize bit life. Inspect bits for wear or damage before use and replace worn bits to maintain hole quality and dimensional accuracy.
