What distinguishes Starrett holesaw sets from competitors is their exceptional tooth geometry and electron beam welding process, which creates an unbreakable bond between the high-speed steel cutting edge and tough alloy backing. This manufacturing precision translates directly into longer tool life, cleaner cuts, and reduced downtime on site. Whether drilling through wood, plastic, plasterboard, or metal up to 5mm thick, Starrett sets deliver consistent performance across diverse materials.

The modular nature of Starrett holesaw sets makes them particularly valuable for tradespeople who need versatility without carrying excessive equipment. Most sets include a comprehensive selection of the most commonly used diameters, typically ranging from 19mm to 127mm, alongside durable storage cases that protect investments and keep everything organised. Quick-change arbors with secure locking mechanisms allow rapid diameter changes without tools, significantly improving productivity during multi-size drilling tasks.

Why Choose Starrett Holesaw Sets?

Starrett's reputation in precision measurement and cutting tools extends seamlessly into their holesaw manufacturing. The brand's commitment to metallurgical excellence means every holesaw features high-speed steel teeth that maintain their edge significantly longer than standard carbon steel alternatives. The proprietary tooth set and variable pitch design reduces vibration and heat build-up, enabling faster drilling speeds whilst minimising material distortion around the cut edge.

Professional tradespeople choose Starrett for their consistency and reliability under demanding conditions. The electron beam welded construction ensures teeth remain securely attached even when drilling through challenging materials or when the saw encounters unexpected obstacles like hidden fixings. This durability translates into lower cost-per-hole over the tool's lifetime, making Starrett sets a sound investment rather than a premium expense.

Innovation drives Starrett's product development, with features like their Constant Pitch technology providing smooth, fast cutting across the entire diameter range. The deep gullet design facilitates efficient chip removal, preventing clogging that can cause binding and premature wear. These engineering advantages mean cleaner holes, reduced operator fatigue, and fewer failed cuts that waste both time and materials.

Quick-Change Arbor Systems: Tool-free arbor changes using secure spring-loaded mechanisms save valuable time on site, whilst positive locking prevents dangerous slippage during operation.

Deep Gullet Configuration: Enhanced chip clearance prevents clogging and binding, particularly important when drilling deep holes or working with materials that produce stringy swarf.

Precision Ground Teeth: Every tooth is individually ground to exact specifications, ensuring balanced cutting forces that reduce vibration and produce cleaner, more accurate holes with minimal operator effort.

Durable Storage Solutions: Heavy-duty cases with custom foam inserts or moulded trays protect holesaws during transport and storage whilst keeping everything organised for quick diameter selection.

Popular Starrett Holesaw Sets

Tooled-Up stocks the most sought-after Starrett configurations to suit different professional requirements. The Starrett General Purpose Sets typically include the most frequently used diameters between 19mm and 76mm, ideal for electricians and plumbers handling standard installations. These comprehensive kits usually feature multiple arbors to accommodate the full diameter range alongside a pilot drill.

Starrett Electrician's Sets are specifically curated with diameters commonly required for electrical installation work, including popular sizes for downlighters, back boxes, and cable entries. These focused sets eliminate unnecessary sizes, reducing weight and bulk for mobile tradespeople.

Professional Contractor Sets represent Starrett's most comprehensive offerings, featuring extended diameter ranges up to 127mm or beyond, multiple arbor types, and additional pilot drills. These premium sets serve contractors who require maximum versatility across diverse applications without maintaining multiple smaller kits.

Specialist Deep Cut Sets incorporate Starrett's extended length holesaws for drilling through thicker materials like structural timbers, insulated walls, and doubled-up panels commonly encountered in renovation and retrofit work.

Safety and Compliance

When using Starrett holesaw sets, operators must follow HSE guidelines for powered drilling equipment. Always secure workpieces firmly before drilling, as holesaws generate significant rotational forces that can cause material spinning if inadequately restrained. Wear appropriate PPE including safety glasses or face shields to protect against swarf and debris ejection, and protective gloves when handling freshly cut holesaws which retain considerable heat.

Select appropriate drill speeds for the material being cut—excessive speed in metal generates dangerous heat and can cause premature tooth failure, whilst insufficient speed in wood may cause burning and binding. Ensure drill drivers have adequate torque capacity and side-handle support for larger diameter holesaws, as sudden binding can cause loss of control. When drilling overhead or in confined spaces, take particular care with swarf removal and maintain secure footing.

Starrett holesaws meet relevant BS EN standards for cutting tool safety. Regular inspection for damaged or missing teeth prevents dangerous breakage during use. Clean holesaws after use to prevent material build-up that can affect performance and balance during subsequent operations.

Frequently Asked Questions

What materials can Starrett bi-metal holesaw sets cut through?

Starrett bi-metal holesaws efficiently cut wood, plywood, chipboard, MDF, plastic, fibreglass, plasterboard, and metals including mild steel, aluminium, copper, and brass up to approximately 5mm thickness. For thicker metals or stainless steel, reduced speeds and cutting lubricant extend tool life significantly.

How do I choose between different Starrett holesaw set sizes?

Consider your most common applications—electricians typically need 19mm to 64mm for standard electrical work, whilst plumbers often require larger sizes up to 127mm for waste pipes. General contractors benefit from comprehensive sets spanning the full range, whereas specialists may prefer focused sets containing only regularly used diameters to minimise carried weight.

Can I purchase individual Starrett holesaws to supplement my set?

Yes, Starrett holesaws are available individually at Tooled-Up, allowing you to replace worn sizes or add specific diameters not included in your original set. The standardised arbor systems ensure compatibility across the range, making it easy to build a customised collection matching your exact requirements.

What's the difference between Starrett's various arbor types?

Starrett offers quick-change spring-loaded arbors for rapid diameter changes without tools, standard threaded arbors for maximum security during heavy-duty applications, and specialised deep-cut arbors for extended reach. Quick-change types prioritise speed for jobs requiring multiple sizes, whilst threaded arbors provide additional stability for larger diameters or challenging materials.

How long should a Starrett holesaw last with professional use?

With appropriate speeds, regular cleaning, and correct application, Starrett bi-metal holesaws typically deliver hundreds of cuts in wood-based materials and dozens in metal before requiring replacement. Actual lifespan depends on material hardness, drilling technique, and maintenance. Using cutting lubricant when drilling metal and avoiding excessive speed significantly extends tool life compared to dry, high-speed operation.
