Sealey AK4734 HSS Cobalt Spot Weld Drill Bit Ø8mm

Sealey AK4734 HSS Cobalt Spot Weld Drill Bit Ø8mm – Twist Drill Bit

The Sealey AK4734 is a premium twist drill bit, expertly crafted for demanding spot weld removal tasks. Manufactured from high-speed steel (HSS) and fortified with cobalt, this 8mm diameter bit ensures enhanced durability and precision when working with tough materials, such as automotive body panels.

• High-Speed Steel (HSS) construction for superior resilience
• 5% Cobalt content for increased heat resistance, extending tool life
• 8mm diameter optimised for spot welds and similar applications
• Split point tip (118°) for accurate, self-centring starts
• Compatible with most standard drilling machines and tools

When compared to standard twist drill bits or non-cobalt alternatives, the Sealey AK4734 stands out thanks to its robust construction and longevity. Where ordinary drill bits can quickly become blunt or overheat when used on high-strength steel, the AK4734’s 5% cobalt content ensures greater resistance to heat and wear. This makes it a reliable upgrade over traditional HSS bits, particularly favoured in professional garages and workshops.
