Description
The 85 Series B Station SQ14 Square Thick Turret Die is a precision lower tool developed for punching nominal 14 × 14 mm square holes. In the shape designation “SQ14,” “SQ” identifies the square profile and “14” represents the nominal side length of 14 mm.
Because this product is the lower die rather than a complete punch-and-die assembly, its actual opening is manufactured according to the required punch-to-die clearance. The finished die opening will normally be slightly larger than the corresponding punch profile. The correct clearance depends on the sheet material, thickness, tensile strength, burr requirements and punching conditions.
The square die is manufactured from DC53 tool steel and heat-treated to a working hardness of HRC 58–60. DC53 provides high compressive strength, wear resistance and dimensional stability, making it suitable for shaped punching applications where the corners of the die are subjected to concentrated stress.
Precision-ground cutting edges and accurately machined square corners help maintain consistent hole dimensions, reduce excessive burr formation and improve alignment with the matching SQ14 punch. The die can be supplied individually as a replacement component or together with a compatible punch, guide and stripping assembly.
WYS Machinery provides customized die clearance, corner geometry, coatings and complete thick turret tooling solutions according to the customer’s machine model, sheet material, thickness and finished-part drawings.

SQ14 Size and Die Clearance
SQ14 identifies the nominal 14 × 14 mm punching profile. It should not automatically be interpreted as the final physical opening of the lower die.
The actual die opening is calculated according to the punch size and specified cutting clearance:
| Item | Description |
|---|---|
| Nominal Hole Profile | 14 × 14 mm square |
| Punch Profile | Designed according to the required finished-hole size |
| Die Opening | Punch profile plus the selected total clearance |
| Clearance Selection | Based on sheet material, thickness and required edge quality |
Correct die clearance helps:
- Produce cleaner square holes
- Control burr height
- Reduce stripping force
- Prevent premature corner chipping
- Minimize slug pulling
- Extend punch and die service life
- Improve dimensional consistency
Customers should provide the sheet material, thickness and required finished-hole tolerance so that the appropriate die clearance can be selected.
Typical Hits Before Regrinding
| Sheet Material | Approximate Hits Before Regrinding |
|---|---|
| Stainless Steel | Approximately 300,000 hits |
| Mild Steel | Approximately 500,000 hits |
These figures are typical reference values rather than guaranteed limits. Actual regrinding intervals depend on the material grade, thickness, tensile strength, clearance, lubrication, machine alignment, punching speed and maintenance conditions.
Because SQ14 is a shaped tool, the square corners should be inspected regularly. Regrinding should be performed before excessive corner rounding, chipping or burr growth occurs.
Typical Tool Service Life
| Tool Profile | Approximate Total Service Life |
|---|---|
| Round Tooling | Approximately 800,000 hits |
| Shaped Tooling | Approximately 600,000–700,000 hits |
| SQ14 Square Die | Refer to the Shaped Tooling Range |
Square tooling is classified as shaped tooling because its corners create higher localized cutting loads than round tooling. Correct clearance, accurate punch-to-die alignment and timely regrinding are particularly important for maximizing the service life of an SQ14 die.
Optional TiN and TiCN Coatings
TiN Coating
TiN provides a hard, low-friction surface that can help improve wear resistance and reduce adhesive material buildup. It is a practical option for general-purpose punching applications when coating is suitable for the selected die configuration.
TiCN Coating
TiCN offers higher hardness and enhanced resistance to abrasive and adhesive wear. It can be considered for stainless steel, higher-strength sheet materials and high-volume punching applications.
Coating selection should be based on the sheet material, thickness, production volume and required tooling performance. For some applications, coating the punch may provide a greater performance benefit than coating the die; the final coating arrangement should therefore be confirmed during tooling design.

Manufacturing Quality
The SQ14 square die is produced using carefully selected DC53 tool steel, controlled heat treatment and precision machining processes.
Accurate grinding of the die surface and cutting edges helps maintain dimensional consistency across all four sides of the square opening. Special attention is given to the corners because they are exposed to greater localized stress and are more susceptible to wear or chipping than straight cutting edges.
The die body, locating features and working opening are manufactured to support accurate positioning within the B Station thick turret system. Proper alignment with the corresponding punch helps produce cleaner holes while reducing uneven wear and excessive lateral force.
Quality control can include:
- Square-opening dimensional inspection
- Corner geometry inspection
- Cutting-clearance verification
- Surface flatness inspection
- Die-height inspection
- Hardness testing
- Locating-feature inspection
- Punch-and-die alignment verification
Tool Maintenance and Regrinding
Regular inspection and timely maintenance help preserve square-hole quality and extend the total service life of the die.
Recommended inspection points include:
- Cutting-edge sharpness
- Corner rounding or chipping
- Burr growth on punched parts
- Uneven wear around the opening
- Die surface damage
- Slug condition
- Punch-to-die alignment
- Lubrication and machine condition
The die should be reground before severe edge wear develops. Regrinding both the punch and die according to their actual condition helps maintain consistent clearance and punching performance.
After regrinding, the tool height and machine setup should be checked before returning the tooling to production.
