Irwin Cobalt Drill Bits at MyToolShed.co.uk

Irwin cobalt drill bits represent a premium solution for professionals and serious DIY enthusiasts tackling the toughest drilling applications. Manufactured with high-speed steel enhanced with cobalt alloy, these drill bits deliver exceptional heat resistance and extended tool life when working with hard metals, stainless steel, and cast iron. Irwin's reputation for engineering robust, reliable tools makes their cobalt range a trusted choice for tradesmen across the UK who demand consistent performance on site.

The Irwin cobalt drill bit collection combines advanced metallurgy with precision manufacturing to create cutting tools that maintain their sharp cutting edges far longer than standard HSS bits. Whether you're a fabricator working with steel daily or a contractor who occasionally needs to drill through demanding materials, Irwin's cobalt offerings provide the durability and accuracy required for professional results.

Why Choose Irwin?

• Superior Heat Resistance: The cobalt alloy construction allows Irwin bits to withstand extreme temperatures generated during high-speed drilling without losing temper or hardness
• Extended Tool Life: Irwin cobalt drill bits last significantly longer than conventional HSS bits, reducing replacement frequency and overall tooling costs
• Precision Ground Tips: Each bit features a carefully engineered point geometry that ensures accurate starting and reduced walking, even on smooth metal surfaces
• Versatile Performance: Designed to excel in hard materials including stainless steel, cast iron, titanium, and other tough alloys that quickly dull standard bits
• Professional Heritage: Irwin's decades of experience in manufacturing cutting tools ensures consistent quality and reliability that tradesmen depend upon

Popular Irwin Products

Whilst specific products may vary, Irwin typically offers cobalt drill bits in comprehensive size ranges from small pilot hole diameters through to larger capacity bits for substantial metalworking projects. Their cobalt range often includes individual bits for precise replacements, as well as convenient multi-piece sets that provide tradesmen with the most commonly needed sizes in a durable storage case. Irwin cobalt jobber length drill bits serve as the workhorse option for general metalworking, whilst stub length variants offer enhanced rigidity for precision engineering applications.

Frequently Asked Questions

What materials can I drill with Irwin cobalt drill bits?

Irwin cobalt drill bits excel when drilling hard metals including stainless steel, cast iron, hardened steel, titanium, and high-tensile alloys. They also perform excellently in softer metals and can be used in wood or plastic, though this represents overspecification for those materials.

How do cobalt drill bits differ from standard HSS bits?

Cobalt drill bits contain a cobalt alloy (typically 5-8%) within the high-speed steel, which significantly increases heat resistance and hardness. This allows them to maintain their cutting edge at higher temperatures and drill through harder materials that would quickly dull standard HSS bits.

Do Irwin cobalt drill bits require special care?

Whilst robust, cobalt bits benefit from proper usage including appropriate cutting speeds, adequate lubrication when drilling metals, and secure storage to protect the precision-ground cutting edges. Avoid excessive pressure—let the bit do the work for optimal performance and longevity.
