85 Series A Station RO10 Round Thick Turret Punch

The 85 Series A Station RO10 Round Thick Turret Punch is designed for producing nominal 10 mm diameter holes on compatible CNC thick turret punch presses.

In the designation “RO10,” “RO” identifies the round punching profile and “10” represents the nominal punch diameter of 10 mm. This clear shape-and-size designation helps customers identify the correct replacement punch and matching die.

This product is supplied as an individual punch, not as a complete punch assembly. The punch guide, stripper, spring components and matching lower die are not included unless specified separately.

The RO10 punch is manufactured from M2 high-speed steel and heat-treated to a working hardness of HRC 58–60. M2 combines cutting-edge hardness, toughness and resistance to softening during repeated punching cycles, making it suitable for high-volume production involving mild steel, stainless steel, aluminum and other sheet materials.

Unlike square and rectangular punches, the round profile has no concentrated corner areas. The cutting force is distributed more evenly around the circumference, helping provide stable punching performance and typically allowing a longer service life than comparable shaped tooling under suitable operating conditions.

WYS Machinery can supply the RO10 punch individually, with a matching lower die or as part of a complete A Station tooling assembly. Punch dimensions, die clearance, cutting-edge geometry and optional TiN or TiCN coating can be selected according to the customer’s material, thickness, machine model and production requirements.

Technical Specifications

Punch vs. Punch Assembly

Customers replacing only the worn cutting component can order the RO10 punch individually. If the guide, stripper, springs or die are also required, the existing assembly structure and machine model should be provided.

RO10 Diameter and Matching Die Clearance

RO10 identifies a nominal punch diameter of 10 mm. The matching lower-die opening must include the selected cutting clearance and will therefore be larger than the punch diameter.

Correct clearance helps:

• Produce cleaner circular holes
• Control burr height
• Reduce required punching force
• Improve slug separation
• Reduce stripping resistance
• Prevent premature cutting-edge wear
• Extend punch and die service life
• Maintain consistent hole dimensions

Customers should provide the sheet material and thickness when ordering the punch and matching die.

Round-Profile Performance

The RO10 round punch provides several advantages for repetitive punching:

• Cutting force is distributed evenly around the circumference
• There are no sharp corners with concentrated stress
• Cutting-edge wear is generally more uniform
• Alignment with the matching die is easier to evaluate
• The profile is suitable for high-frequency punching
• Regrinding can restore the complete circular cutting edge
• Stable geometry supports consistent hole quality

These characteristics make round punches widely used for general sheet metal production, perforated layouts, mounting holes and ventilation patterns.

Typical Hits Before Regrinding

These values are typical references, not guaranteed performance limits. Actual regrinding intervals depend on:

• Sheet material grade
• Material thickness
• Tensile strength
• Punch-to-die clearance
• Lubrication
• Coating selection
• Punching speed
• Machine alignment
• Stripping conditions
• Tool maintenance

The cutting edge should be reground before excessive rounding or burr growth develops.

Typical Tool Service Life

RO10 belongs to the round-tooling category. Its circular cutting geometry generally provides more uniform load distribution than square or rectangular punches.

Actual service life still depends on correct clearance, suitable lubrication, machine alignment and timely regrinding.

Optional TiN and TiCN Coatings

TiN Coating

TiN provides a hard, low-friction surface that helps reduce adhesive wear and material buildup. It is suitable for many general-purpose punching applications involving mild steel and other common sheet materials.

TiCN Coating

TiCN offers higher hardness and enhanced resistance to abrasive and adhesive wear. It is particularly useful for stainless steel, higher-strength materials and high-volume punching.

The appropriate coating should be selected according to the material, thickness, punching frequency and required tool life.

Typical Applications

The RO10 A Station round punch is suitable for producing 10 mm circular holes in:

• Electrical cabinets and control panels
• Switchgear and distribution equipment
• Sheet metal housings
• Electronic equipment enclosures
• HVAC and ventilation components
• Machinery covers and protective guards
• Metal furniture and storage systems
• Automotive sheet metal components
• Appliance panels
• Mounting plates and brackets
• General precision sheet metal parts

Typical hole functions include:

• Bolt and screw clearance holes
• Component mounting holes
• Cable-entry openings
• Locating holes
• Ventilation patterns
• Perforated sheet layouts
• Assembly and fastening points
• General-purpose circular openings

Manufacturing Quality

The RO10 punch is manufactured using carefully selected M2 high-speed steel, controlled heat treatment and precision grinding.

Manufacturing control focuses on:

• Accuracy of the 10 mm punch diameter
• Roundness of the cutting profile
• Cutting-edge sharpness
• Concentricity between the punch tip and body
• Surface finish
• Punch length
• Heat-treatment consistency
• Fit with compatible A Station guide components

Accurate concentricity and roundness help maintain uniform clearance around the matching die. This supports consistent hole quality and reduces uneven side wear.

Tool Maintenance and Regrinding

The RO10 punch should be inspected regularly for:

• Cutting-edge rounding
• Uneven circumferential wear
• Adhesive material buildup
• Surface scratches
• Increased hole burrs
• Excessive stripping force
• Misalignment with the matching die
• Abnormal punching noise

Timely light regrinding removes less material and helps preserve the usable punch length. After regrinding, the punch length and assembly settings should be checked before returning the tool to production.
