Gole Precision Tools Pvt. Ltd. manufactures carbide-tipped gun reamers in single cutting edge, double cutting edge, and multiple cutting edge configurations — each suited to specific production requirements, feed rate targets, and bore finish demands.
Single, Double, and Multiple Cutting Edge — What Each Configuration Does
The number of cutting edges on a gun reamer is not a matter of preference — it is an engineering decision based on the bore requirement, workpiece material, and production throughput.
Best suited for: tight tolerance bores, deep length-to-diameter ratios, applications where bore straightness is critical across the full depth.
Best suited for: medium-volume production, bores requiring a balance of finish quality and cycle time, materials that respond well to balanced cutting forces.
Best suited for: hydraulic valve body reaming, tandem master cylinder bores, transfer line production, any application where throughput is the primary objective alongside acceptable finish and tolerance.


Primary Applications
Our Gun reamers are specified across precision engineering sectors where bore finish, diameter tolerance, and cylindricity directly affect component function.
Hydraulic Valve Bodies Valve spool bores require tight diameter tolerance and a consistent surface finish to ensure proper sealing and spool movement without leakage or stiction. Gun reaming in a single pass eliminates the variation introduced by multi-pass conventional reaming.
Tandem Master Cylinders The tandem master cylinder bore is a classic gun reaming application — deep, precise, and produced in high volume. The bore finish directly affects piston seal life and hydraulic system performance. Multi-edge gun reamers are standard on these production lines.
Hydraulic Cylinders and Actuators Deep bores in hydraulic cylinder bodies demand straightness and finish that conventional reamers cannot maintain at depth. Gun reamers maintain bore geometry from entry to exit.
Fuel System Components Injector body bores, pump housings, and fuel rail components require consistent finish and diameter control across production batches. Gun reaming delivers the repeatability these applications demand.
Pneumatic Components Compressor bodies, valve blocks, and pneumatic actuator housings — wherever a finished bore must seal reliably against a moving element.
General Precision Engineering Any pre-drilled bore requiring final diameter control, improved surface finish, and cylindricity correction in a single productive pass.
