Whether you're working with wood, metal, plastic, or composite materials, Tooled-Up stocks Irwin holesaws in an extensive range of diameters to accommodate everything from small cable routing holes to large-diameter apertures for pipework and electrical installations.

The Irwin philosophy centres on innovation and longevity, with each holesaw featuring carefully engineered tooth geometry and premium materials that resist wear even under the most punishing site conditions. Their arbor systems incorporate quick-change mechanisms and reinforced shanks that eliminate slippage and provide reliable performance across thousands of cuts.

Why Choose Irwin Holesaws & Arbors?

Irwin's reputation in the cutting tools sector stems from over a century of manufacturing excellence and continuous product development. Their holesaws utilise bi-metal construction that combines high-speed steel cutting edges with flexible alloy backing, creating a cutting tool that remains sharp longer whilst resisting tooth breakage and cracking. This translates directly into lower cost-per-hole and reduced downtime on site.

The brand's commitment to user productivity is evident in features such as their variable pitch tooth design, which reduces vibration and delivers smoother cutting action with less chatter. Irwin holesaws also incorporate optimised gullet depths that improve chip clearance, preventing clogging and maintaining cutting speed even through thick materials. Their arbor systems feature robust threaded connections and positive-locking mechanisms that ensure concentricity and eliminate the frustration of bits working loose during operation.

Professional tradespeople appreciate Irwin's focus on practical design details, including clearly marked sizing on each holesaw for quick identification, and colour-coded components that simplify system compatibility. The brand's extensive diameter range means you can source the exact size needed without resorting to improvised solutions that compromise quality.

Key Features of Irwin Holesaws & Arbors

Bi-Metal Construction: Irwin holesaws feature high-speed steel cutting edges electron-beam welded to tough alloy backing material, providing exceptional durability and heat resistance that outlasts standard carbon steel alternatives by a significant margin.

Variable Tooth Pitch: Advanced tooth geometry with varying pitch reduces vibration and noise whilst improving cutting speed and producing cleaner entry and exit holes with minimal burr formation.

Optimised Gullet Design: Deep, precisely formed gullets efficiently evacuate chips and swarf from the cutting zone, maintaining performance and preventing binding even when drilling through thick materials or creating stacked holes.

Quick-Change Arbor Systems: Tooled-Up's Irwin arbor range includes quick-release mechanisms that allow rapid holesaw changes without tools, dramatically improving productivity when working with multiple diameters.

Universal Shank Compatibility: Irwin arbors feature standard hex shanks compatible with both handheld drills and magnetic drilling machines, providing versatility across different power tool platforms.

Reinforced Pilot Bits: Heavy-duty pilot bits with hardened tips ensure accurate hole positioning and resist deflection, even when drilling at extreme angles or through challenging materials.

Popular Irwin Holesaws & Arbors

Bi-Metal Holesaw Sets: Comprehensive kits containing the most commonly required diameters along with compatible arbors, offering excellent value and covering the majority of typical site requirements in a convenient storage case.

Individual Bi-Metal Holesaws: Available in diameters from 14mm through to 210mm, allowing precise selection for specific applications and replacement of worn cutters from existing sets.

Standard Arbors: Traditional threaded arbor systems providing secure holesaw mounting with proven reliability for general drilling applications across all material types.

Quick-Change Arbors: Professional-grade arbors featuring tool-free holesaw changing mechanisms, ideal for electricians and plumbers who regularly switch between multiple diameters throughout the working day.

Deep Cut Holesaws: Extended-depth variants for drilling through thick materials such as doubled joists, solid doors, and structural timbers where standard depth holesaws cannot reach.

Safety and Compliance

When using Irwin holesaws and arbors, always ensure your power drill or magnetic base machine is appropriate for the holesaw diameter and material being cut. Large diameter holesaws generate significant torque, particularly when breaking through, so maintain a firm grip and use auxiliary handles where fitted. Wear appropriate PPE including safety glasses to protect against flying chips and swarf.

Ensure arbors are correctly tightened before operation and check the pilot bit protrudes sufficiently beyond the holesaw teeth to properly locate the cut. When drilling metal, use appropriate cutting lubricant to reduce heat buildup and extend tool life. Always allow the tool to reach full speed before engaging the workpiece, and maintain steady pressure without forcing.

For electrical work involving existing installations, always isolate circuits and verify dead before drilling near cables or existing services. Follow HSE guidance regarding safe working practices, particularly when working at height or in confined spaces. Regularly inspect holesaws for damaged or missing teeth, and replace worn cutters to maintain cutting performance and safety.

Frequently Asked Questions

What's the difference between bi-metal and standard carbon steel holesaws?

Irwin bi-metal holesaws feature high-speed steel cutting edges welded to a flexible backing, providing significantly longer life and heat resistance compared to carbon steel alternatives. Bi-metal construction is essential for cutting metal and provides superior performance and durability in all materials, making them the professional choice for regular use.

Which arbor system should I choose for my Irwin holesaws?

Standard threaded arbors are reliable and economical for occasional use or when working with a single diameter. Quick-change arbors are ideal for professionals who regularly switch between multiple holesaw sizes, eliminating the time spent threading holesaws on and off and significantly improving productivity on multi-diameter jobs.

Can Irwin holesaws cut through stainless steel?

Yes, Irwin bi-metal holesaws are designed to cut stainless steel, though it's a demanding material that requires slower speeds, constant cutting pressure, and generous application of cutting lubricant. Expect slower progress and increased wear compared to mild steel, and ensure your drill has sufficient power and battery capacity for the extended cutting time required.

How do I prevent my holesaw from binding or jamming?

Regularly withdraw the holesaw to clear accumulated chips, particularly when cutting deep holes or working with materials that produce long stringy swarf. Use appropriate cutting speeds - too fast generates excessive heat whilst too slow can cause teeth to rub rather than cut. Ensure the arbor pilot bit is sharp and properly locating the cut, and maintain steady pressure without forcing.

What diameter holesaw do I need for standard UK electrical socket boxes?

Standard 35mm single and double socket boxes typically require a 60-65mm diameter holesaw for plasterboard installations. For deeper metal boxes in masonry, a 68mm or 70mm diameter may be needed. Always check the specific box manufacturer's recommendations, and remember that it's better to cut slightly oversize than struggle to fit a box into an undersized hole.
