Key Features of Starrett Drilling Accessories

Advanced Material Technology: Starrett employs high-speed steel (HSS), cobalt steel, and carbide-tipped constructions across their drilling accessory range, with each material selected to optimise performance in specific applications. Their proprietary heat treatment processes maximise hardness whilst maintaining the toughness required to resist breakage under demanding conditions.

Precision Manufacturing: Every Starrett drill bit is precision-ground to exacting tolerances, ensuring accurate hole sizes and straight drilling without walking or wandering. This precision reduces the need for secondary finishing operations and ensures components fit together properly the first time.

Specialist Coatings: Many Starrett drilling accessories feature advanced surface treatments such as titanium nitride (TiN), titanium carbonitride (TiCN), or black oxide coatings. These coatings reduce friction, dissipate heat more effectively, and prevent material adhesion, all of which contribute to extended tool life and improved cutting performance.

Optimised Geometries: Starrett's drill bit point angles, flute designs, and cutting edge geometries are engineered for specific materials and applications. This attention to detail ensures efficient chip evacuation, reduces cutting forces, and produces cleaner holes with minimal burr formation.

Universal Shank Compatibility: Starrett drilling accessories feature standardised shanks compatible with common chuck systems, ensuring they work seamlessly with existing power tools, whether cordless drills, pillar drills, or magnetic drilling machines.

Safety and Compliance

When using Starrett drilling accessories, adherence to UK Health and Safety Executive (HSE) guidelines is essential. Always wear appropriate personal protective equipment including safety glasses or face shields to protect against flying debris, and ensure workpieces are securely clamped before drilling to prevent rotation or movement.

Select the correct drilling speed for the material and drill bit size being used, as excessive speed can cause overheating, premature wear, or tool failure. When drilling metal, use appropriate cutting fluid to lubricate the cutting edges, dissipate heat, and improve surface finish whilst extending tool life.

Inspect Starrett drilling accessories before each use for signs of damage, excessive wear, or dullness. Damaged or worn drill bits require increased pressure to cut effectively, which increases the risk of breakage or loss of control. Replace worn accessories promptly to maintain safe, efficient operation.

Ensure power tools used with Starrett drilling accessories are properly maintained, with chucks tightened securely and 240V corded tools protected by appropriate circuit protection. When working on site, use residual current devices (RCDs) with 240V equipment to provide additional protection against electrical hazards.

Frequently Asked Questions

What's the difference between Starrett's HSS and cobalt drill bits?

Starrett's high-speed steel (HSS) drill bits are excellent for general-purpose drilling in wood, plastic, and mild steel. Cobalt drill bits contain cobalt alloy (typically 5-8%), which increases heat resistance and hardness, making them ideal for drilling harder materials such as stainless steel, cast iron, and hardened alloys. Whilst cobalt bits cost more initially, they maintain their cutting edge significantly longer when working with tough materials.

How do I know when to replace my Starrett drill bits?

Replace Starrett drill bits when you notice increased drilling pressure required, excessive heat generation, squealing sounds during cutting, or visibly worn or chipped cutting edges. If holes are no longer clean or the drill bit tends to wander rather than cutting straight, it's time for replacement. Regular inspection and timely replacement ensure safe operation and maintain the quality of your work.

Can Starrett drilling accessories be resharpened?

Larger Starrett drill bits (typically above 10mm) can be resharpened using appropriate grinding equipment, though this requires skill to maintain the correct point angle and cutting edge geometry. For smaller bits and specialist accessories like coated drill bits, replacement is generally more cost-effective than resharpening. Starrett hole saws cannot be practically resharpened and should be replaced when teeth become dull.

Are Starrett drilling accessories suitable for use with cordless drills?

Yes, Starrett drilling accessories are fully compatible with cordless drills, provided the drill has sufficient power and battery capacity for the application. When using larger drill bits or hole saws with cordless tools, ensure your drill provides adequate torque and consider using a lower speed setting to prevent motor strain. For heavy-duty applications, a corded 240V drill may provide more consistent performance.

What cutting fluid should I use with Starrett metal drill bits?

For drilling mild steel with Starrett bits, use a general-purpose cutting fluid or soluble oil. When drilling aluminium, use a specialist aluminium cutting fluid or paraffin to prevent material adhesion. For stainless steel, use a high-quality extreme-pressure (EP) cutting fluid. Always apply cutting fluid generously and continuously during drilling to maximise tool life and hole quality. Some materials like brass and cast iron can be drilled dry, though lubrication still improves results.
