Built Blue Since 1940 Explore our high-performance combined drills, countersinks, and complementary finishing tooling stocked and distributed for Canadian industrial buyers and machine shops.
Double-ended high-speed steel center drill for precise 60° tailstock centering and starter hole drilling in mild steel and non-ferrous alloys.
High-precision aluminum oxide feed-control grinding wheels for centerless shank grinding and tool steel blank manufacturing.
Low-noise mounted abrasive flap wheel designed for deburring drill holes, smoothing countersinks, and internal diameter finishing.
Reinforced ultra-thin cutting discs engineered for clean pre-cutting of alloy steel round bars and drill rod stock in machine shops.
Super-abrasive diamond cup wheel (220 grit) designed for resharpening solid carbide center drills, step drills, and end mills.
Turbo-segment diamond cup wheel for heavy surface preparation, weld blending, and chamfer clean-up on structural metals.
High-removal rate grinding wheel optimized for heavy metalworking shops, preparing structural weldments, and chamfering edges.
5-inch abrasive cutoff wheel designed for smooth, burr-free sectioning of solid bar stock prior to CNC lathe center drilling.
Founded with a commitment to industrial tooling excellence in 1940, Century Drill & Tool has engineered specialized cutting and threading solutions for over eight decades. When supplying the Canadian market—where machining conditions range from high-volume automotive production in Southern Ontario to extreme-duty oilfield fabrication in Alberta—tool reliability under thermal stress is non-negotiable.
Our center drills and combined countersink tools are specifically targeted to solve material-specific machining challenges in key Canadian industrial sectors.
High-speed centering of drive shafts, axels, and rotor hubs in Windsor, Hamilton, and Oshawa manufacturing plants requiring zero-runout 60° lathe center pilot holes for precision grinding operations.
Machining titanium alloys, Inconel 718, and 7075-T6 aluminum components in Quebec's aerospace hub using M35 Cobalt and Solid Carbide center drills with 135° split points to prevent work hardening.
Heavy tailstock center drilling on forged drill collars, valve bodies, and pump shafts in Alberta's energy sector. Type B bell-type center drills protect 60° centers from burrs during rough shop handling.
Re-centering and re-machining worn crusher shafts, conveyor rolls, and heavy gear assemblies. Heat-resistant M42 center drills handle tough maintenance alloys under field lathe conditions.
Precision center hole countersinking on stainless steel prop shafts and rudder pins. Radius Type R center drills distribute heavy axial tailstock thrust without causing stress concentrations.
Versatile imperial center drill set deployment across thousands of job shops for fast, accurate countersinking, starter hole spotting, and live-center alignment on manual and CNC lathes.
Avoid premature tip breakage and poor center quality. Reference our engineering standard guide for choosing center drill styles based on workpiece material and machining objectives.
| Center Drill Type | Included Angle | Design Characteristics | Target Workpiece Material | Key Machining Advantage |
|---|---|---|---|---|
| Type A (Plain Form) | 60° Countersink | Standard straight 60° cone with 118° drill point tip | Mild Steel (A36, 1018), Brass, Aluminum, Plastics | Economical standard center for conventional lathe turning between centers. |
| Type B (Bell Type) | 60° / 120° Protected | Secondary 120° chamfer protects the primary 60° bearing cone | Forgings, Heavy Castings, 4140/4340 Alloy Steels | Prevents center hole damage from handling, drop impacts, and deburring burrs. |
| Type R (Radius Form) | Curved Radius | Convex curved transition profile instead of straight cone | Tool Steels (D2, O1), Stainless Steel 316L, Titanium | Reduces friction; accommodates slight tailstock misalignment without point loading. |
| M35 Cobalt (5% Co) | 60° / 135° Split Pt | High heat hardness rating (HRC 66-67) with web reduction | Work-Hardening Stainless, Inconel, Hardened Die Steels | Resists thermal breakdown up to 650°C; eliminates center drill walk on angled faces. |
| Solid Micrograin Carbide | 60° Form | Extreme rigidity, high wear resistance, no flexibility | High-Speed CNC Production, Pre-Hardened Steels (>45 HRC) | Maximizes tool life in automated high-RPM CNC turning centers without burring. |
Because center drill pilot tips have low peripheral speeds while the larger countersink shoulder runs at high surface feet per minute (SFM), improper feed rate is the #1 cause of breakage in Canadian machine shops.
How Canadian manufacturing modernization, supply chain reshoring, and advanced metallurgies impact tooling specifications for machine shops and OEM buyers.
With automated robotic loading on CNC turning centers growing across Ontario and Quebec, machine shops require center drills with tight concentricity tolerances (<0.005mm) to prevent automatic tool changer jamming and inconsistent countersink depths.
Canadian federal initiatives promoting domestic critical mineral processing and military hardware fabrication have increased demand for premium M35/M42 Cobalt center drills capable of cutting superalloys locally without depending on imported low-tier tools.
While Western Canada's energy sector continues using traditional Imperial sizes (#1 through #8), aerospace and medical machining in Eastern Canada mandate DIN 333 metric specifications. Century provides dual-stocked options to service both standards seamlessly.
