Extended Range Punches Metric X Tip

This extended-range metric punch is used in progressive stamping and forming dies where the tooling must maintain stable engagement over a longer stroke. The extended body length helps control punch travel, supporting repeatable forming and consistent part geometry from cycle to cycle.

In automotive connector and bracket forming, punch wear and alignment directly affect hole size and burr formation. The X-tip geometry is suited for reliable material engagement, helping the punch maintain predictable cutting/forming action across the full travel.

For die and punch maintenance programs, this variant is designed as a metric option that supports compatibility with standard die sets, making it practical for replacement and tooling refurbishment without redesigning the entire tool block.

• Progressive forming: controlled long-travel stroke for stable output
• Stated tip shape (X) for consistent material engagement
• Metric tooling fit for maintenance-friendly die assembly

The provided data focuses on dimensional and tip-geometry variants (tip shapes H, J, K, N, O, R, V, X, Y, Z). No specific steel grade, hardness (HRC), or heat-treatment state is included in the specifications, so those properties should be confirmed from your tooling purchase documentation or drawings for this exact DAYTON series.

In general, extended-range punches rely on hardened tool steels to balance wear resistance with toughness under bending and impact loads during stamping. Higher hardness typically improves edge life, while excessive hardness can reduce toughness and increase chipping risk.

• Confirm steel grade (e.g., SKD/H13 or equivalent) and heat treatment state (quench & temper, nitriding, etc.) from the product datasheet
• Hardness (HRC) and coating details should be verified per tip shape and diameter option
• Without grade confirmation, only dimensional suitability can be assured

Select the punch by matching the shank diameter (D) and overall length (L) range to your die layout. The series offers D = 40, 45, 50, 56, 63 mm and L = 63 to 100 mm, which should be chosen to ensure proper guide engagement and sufficient exposure for the required stroke.

Then verify the working point size using L1 (point length) = 25 to 30 mm. This point length affects how much material is engaged and is critical for controlling forming depth and cut quality.

Finally, match the geometry parameters to your block clearances and alignment features:

• P options: 20 to 39.95, 25 to 44.95, 30 to 49.95, 35 to 55.95, 40 to 62.95 mm
• W options: 8 to 39.95, 9 to 44.95, 10 to 49.95, 11 to 55.95, 12 to 62.95 mm
• R options: 0.2 to 19.975, 0.2 to 22.475, 0.2 to 24.975, 0.2 to 27.975, 0.2 to 31.475 mm

Tip shape (including X) must match the process requirement, while tolerances/fit should follow your die set drawing because no tolerance values are provided in the input data.
