If you’ve ordered bar stock and spent time cleaning up a rough end before machining, you already know cut quality matters. The method used at the saw affects every operation that follows, from chucking to finishing.
At O’Hare Precision Metals, we use cold saw blades on automated CNC saws and manual power bar saws. Our customers notice the difference immediately: cleaner faces, tighter lengths, and less corrective work before machining begins.
Why Cold Saw Cutting Outperforms Bandsaw and Friction Methods
Cold saw cutting pushes heat into the chip, not into the bar. That keeps the cut face stable, square, and free from the hardened edge that friction-based and hot sawing methods leave behind. The result is a superior surface finish with low roughness, ready for the next operation.
Bandsawing causes blade deflection at the back of the cut on round bar stock. That deflection produces a face that isn’t truly square. Friction sawing generates heat that can alter surface hardness at the end of the bar, which creates problems on heat-treated grades like 4140 or corrosion-resistant grades like 316 stainless.
Tighter Length Tolerances Right Off the Saw
Our cold saw operation exceeds standard length tolerances when cutting to your custom dimensional requirements. That means your machinist removes less corrective stock, cycle times stay consistent, and material yield improves across a full production run.
We also use specialized saws for shorter bar lengths. Shorter pieces vibrate more during the cut, which opens up tolerance and degrades the end face. Our tooling controls that vibration, so cut quality stays consistent regardless of bar length.
CNC Automated and Manual Saw Capabilities
Our automated CNC saws cut round bar stock up to 7 inches in diameter, covering most profiles that come through a production shop. For jobs that need more hands-on control, manual and power bar saw options are available.
We cut across all materials we carry, including stainless steel, carbon steel, alloy steel, tool steel, aluminum, titanium, nickel, high temperature alloys, brass, copper, and bronze. Clean cuts with minimal waste on every material.
Saw Cutting Combined With In-House Services
Saw cutting at O’Hare connects directly to our other services. If your bars need cutting and then precision grinding, we handle both on-site. Our centerless grinding holds tolerances up to .0001 inches with surface finishes of 8 micro inches or better.
Chamfering pairs naturally after a cold saw cut. CNC and manual chamfering remove edge sharpness and prepare the bar for assembly or further machining. Our packaging service bundles finished bars in a tube and collar wrap, custom wood boxes, or paper wrap in bundles to keep cut ends protected in transit.
Quality and Certification Behind Every Cut
We’re ISO 9001:2015 certified, and that standard applies to every saw cutting job we run. Quality control inspections happen at each phase of operation, so your dimensional requirements are verified before anything ships.
Every order, whether it’s a simple cut to length or a multi-step job combining saw cutting, grinding, and chamfering, moves through the same inspection process. You get bars that meet spec, not bars you have to measure and sort after delivery.

FAQs
What diameter range do your cold saws handle?
Our automated CNC saws cut round bar stock up to 7 inches in diameter. Manual and power bar saw options are also available.
Why does cold saw cutting outperform bandsawing?
Cold saw cutting produces a cleaner, squarer face with low roughness and tighter length tolerances. Bandsawing causes blade deflection and higher surface roughness.
What materials can you cold saw cut?
We cut stainless steel, carbon steel, alloy steel, tool steel, aluminum, titanium, nickel alloys, brass, copper, and bronze.
Can saw cutting be combined with grinding or chamfering?
Yes. We offer saw cutting, centerless grinding, chamfering, turning, milling, burnishing, polishing, and packaging in-house with inspections at each phase.
