Why Choose Starrett Holesaws?

Starrett holesaws stand apart from competitors through their exceptional build quality and cutting performance. The company's bi-metal holesaws combine a high-speed steel cutting edge with a flexible alloy steel body, creating a tool that maintains sharpness whilst resisting breakage under stress. This construction method results in holesaws that outlast standard carbon steel alternatives by a significant margin, making them a cost-effective choice despite their premium positioning.

The brand's dedication to innovation is evident in their Quick Release arbor system, which allows rapid holesaw changes without tools—a feature that saves valuable time when switching between different diameter cuts. Starrett's variable pitch tooth design reduces vibration and noise whilst improving cutting speed, making the work more comfortable for operators and producing cleaner holes with less burring. Their constant pitch holesaws excel in thinner materials, whilst deep cut models tackle thick steel plates and layered materials that would quickly defeat lesser tools.

Key Features of Starrett Holesaws

Bi-Metal Construction: Starrett's signature bi-metal design bonds M42 high-speed steel teeth to an alloy steel body, creating holesaws that combine hardness with flexibility. This prevents tooth stripping whilst maintaining the sharp cutting edge essential for clean holes.

Variable Pitch Tooth Pattern: The varying tooth spacing reduces vibration and chattering during cutting, resulting in smoother operation, less operator fatigue, and superior hole quality. This design also helps prevent tooth clogging when cutting through materials that produce long swarf.

Quick Release Arbor System: Starrett's tool-free quick release mechanism allows instant holesaw changes, dramatically improving productivity when working through multiple diameter requirements. The positive locking ensures secure attachment even under heavy cutting loads.

Deep Cut Models: Extended depth holesaws in the Starrett range handle thick materials and stacked panels, with increased body length that maintains rigidity during extended cutting operations.

Fast Cut Technology: Selected Starrett holesaws feature aggressive tooth geometry optimised for rapid cutting in wood and softer materials, ideal for high-volume installation work where speed matters.

Precision Ground Teeth: Every tooth is precisely ground to exacting tolerances, ensuring consistent cutting performance and extended tool life. This attention to detail produces cleaner holes requiring less finishing work.

Popular Starrett Holesaws

Constant Pitch Bi-Metal Holesaws: The workhorse of the Starrett range, these holesaws handle materials up to 3mm thick with exceptional efficiency. Available in sizes from 14mm to over 150mm diameter, they're perfect for general trade work across wood, plastic, and thin metals.

Variable Pitch Bi-Metal Holesaws: Designed for heavier materials including thick steel plate, stainless steel, and cast iron. The variable tooth pattern delivers smoother cutting with reduced vibration, making them ideal for demanding metalworking applications.

Fast Cut Holesaws: Optimised for rapid cutting in wood, plywood, chipboard, and plastic, these holesaws feature aggressive tooth geometry that removes material quickly whilst maintaining clean cut quality—perfect for high-volume electrical and plumbing installations.

Deep Cut Models: Extended depth variants handle materials from 38mm to 51mm thick, essential for cutting through doubled joists, thick steel sections, and multi-layer panel construction common in modern building methods.

Carbide Tipped Holesaws:For the most abrasive materials including ceramic tiles, fibreglass, brick, and hard plastics, Starrett's carbide-tipped models deliver where bi-metal holesaws would quickly dull. These specialist cutters excel in bathroom installations and renovation work.

Safety and Compliance

When using Starrett holesaws, always follow HSE guidance for safe operation of power tools. Secure workpieces properly using clamps or vices—never hold material by hand whilst drilling. Wear appropriate personal protective equipment including safety glasses to protect against flying swarf and metal fragments, and hearing protection when operating at high speeds or for extended periods.

Ensure drill speed settings are appropriate for the material being cut and holesaw diameter. Excessive speed can cause premature tooth wear and dangerous overheating, whilst insufficient speed may cause binding. Always allow the holesaw to reach full speed before engaging the workpiece, and apply steady, controlled pressure—forcing the cut increases the risk of tooth breakage and binding.

When cutting metal, use appropriate cutting lubricant to reduce heat buildup and extend holesaw life. Clear swarf regularly to prevent clogging, particularly in deep cuts. Be aware that freshly cut holes have sharp edges requiring deburring, and metal surfaces will be hot immediately after cutting. Always disconnect power tools before changing holesaws, even with quick release systems, and inspect holesaws regularly for damaged or missing teeth, replacing worn tools before they become unsafe.

Frequently Asked Questions

What's the difference between Starrett's constant pitch and variable pitch holesaws?

Constant pitch holesaws feature uniform tooth spacing and excel in materials up to 3mm thick, making them ideal for sheet metal, thin steel, and general trade work. Variable pitch holesaws have alternating tooth spacing that reduces vibration and are designed for thicker materials, stainless steel, and more demanding cutting applications. For most electrical and plumbing work, constant pitch models are sufficient, whilst mechanical engineers and fabricators often prefer variable pitch for heavy steel work.

Can I use Starrett holesaws with any power drill?

Starrett holesaws work with any drill that accepts standard arbors, including corded drills, cordless drills, and magnetic drilling machines. However, for larger diameter holesaws (above 50mm) or cutting thick metal, a powerful drill with adequate torque is essential. A quality 18V cordless drill handles most trade applications, but for regular heavy-duty use, a corded drill or low-speed drill provides more consistent power. Starrett's Quick Release arbors fit standard 7/16-inch hex chucks or can be used with standard three-jaw chucks.

How do I know when my Starrett holesaw needs replacing?

Signs that a holesaw requires replacement include visibly damaged or missing teeth, excessive heat generation during cutting, significantly increased cutting time compared to when new, or a tendency to wander off-centre when starting cuts. Starrett holesaws can be resharpened professionally if teeth are worn but intact, though many tradespeople find replacement more economical given the time involved. Regular cleaning and proper storage extend holesaw life considerably—remove accumulated swarf and apply a light oil coating to prevent rust.

What cutting speed should I use for different materials?

For mild steel and general metalwork, operate at approximately 60-80 RPM for holesaws above 50mm diameter, increasing to 150-200 RPM for smaller sizes. Stainless steel requires slower speeds (40-60 RPM for large diameters) and generous lubrication. Wood and plastic can be cut at much higher speeds—300-500 RPM depending on diameter—without lubrication. Always start slowly to establish the pilot hole, then increase to working speed. Excessive speed causes rapid tooth wear and overheating, whilst too slow a speed may cause binding or work hardening in metals.

Do Starrett holesaws work with other manufacturers' arbors?

Starrett holesaws use industry-standard arbor threads, so they're generally compatible with quality arbors from other manufacturers. However, Tooled-Up recommends using genuine Starrett arbors, particularly their Quick Release system, to ensure optimal performance and safety. The precise engineering of Starrett arbors maintains concentricity and reduces vibration, directly affecting cut quality and tool life. Non-genuine arbors may not locate the holesaw as accurately or provide equivalent thread engagement, potentially causing wobble or, in extreme cases, holesaw detachment during operation.
