When drilling cycle times, positional accuracy, and tool longevity are critical to your shop floor’s profitability, Clarkson-Osborn Tools delivers. As Canada’s premier authority on high-precision cutting tools, we engineer and supply an elite range of industrial twist drills designed to tackle the absolute toughest workpiece materials. With our selection of heavy-duty mining components, our comprehensive drill bits ensure minimal tool deflection, optimized chip evacuation, and a drastically reduced cost-per-hole.
Explore our massive inventory of industrial-grade drills. Whether your setup requires short and ultra-rigid stub drills for high-torque applications, versatile jobber lengths for general fabrication, or heavy Morse taper shanks for large-diameter drilling, we stock the advanced substrates and specialized geometries required to eliminate unexpected machining downtime.
Choosing the right drill bit configuration involves matching your machine’s rigidity, spindle speed, and workpiece hardness to the proper drill length, tip angle, and surface treatment. Our extensive catalog spans a diverse array of professional-grade sub-categories engineered to handle specialized production tasks.
The construction of the drill’s tip and its outer surface chemistry drastically alter performance:
To stop premature chipping, overheating, and tool failure, match your industrial material group to the correct metallurgical substrate:
| Drill Substrate Type | Best Used For | Key Advantages |
|---|---|---|
| Solid Carbide | Hardened steels, cast iron, abrasive composites, high-speed CNC. | Ultimate hardness, incredible thermal threshold, handles extreme RPMs. |
| Carbide Tipped | Cost-effective hardened steel drilling, rugged cast materials. | Combines the raw cutting power of carbide with a tough, shock-absorbing HSS body. |
| Cobalt Alloys (M35/M42) | Stainless steels, titanium, high-tensile alloys, structural steel. | Superior red-hardness, maintains sharp cutting edge under immense heat. |
| High-Speed Steel (HSS) | Mild carbon steels, aluminum, brass, copper, general workshop maintenance. | Superior structural toughness, high resistance to shock/vibration, highly economical. |
For over 50 years, Clarkson-Osborn Tools has been Canada’s leading partner for high-precision manufacturing, fabrication, and maintenance engineering. We provide more than just stock numbers—we provide field-tested production solutions:
You should choose a 135° split point when drilling tough, hard, or work-hardening materials like stainless steel, or when drilling into curved/unstable surfaces. The split point creates a self-centering action that prevents the tool from sliding or “walking” across the metal, protecting your workpiece from scuffing and reducing mechanical strain.
TiN is a microscopic, ultra-hard ceramic coating applied to the drill body. It significantly reduces the coefficient of friction, allowing chips to slide effortlessly up the flutes while acting as a thermal barrier. This enables you to run higher feed rates and speeds while expanding your total tool lifespan by up to 300% to 400% compared to uncoated bits.
Deep-hole drill breakage is typically caused by chip compaction inside the flutes, causing the drill to bind and snap under torsional stress. To prevent this, ensure you use a high-performance cutting fluid, periodically utilize a “peck-drilling” cycle to clear out packed chips, or upgrade to a parabolic flute geometry designed specifically for deep, seamless evacuation.
