DAYTON Regular Punch Blanks - Metric

This metric punch blank is used as a pre-machined forging/stock form for building punch tooling in injection molding-related downstream operations such as sheet metal blanking and forming dies, where punch alignment and consistent cutting edges directly affect part dimensional stability.

Progressive tooling for automotive connector housings (contact carrier profiles): Use the regular punch blank geometry to maintain predictable shank fit and guidance in station blocks. The availability of PS, M2, and A2 options lets tooling engineers select hardness/wear resistance for the expected cycle rate.

• Medical device housing manufacturing: In finer forming setups where burr control and stable cutting performance matter, match the punch blank length to accommodate guide retention and die access while keeping shank dia. within 4–32 mm.
• Appliance and electronics sheet forming: For repeated blanking operations, the blank’s metric sizing supports standardized die construction and repeatable assembly in progressive or transfer tooling.

The metric shank diameter and length ranges (D 4–32 mm, L 40–100 mm and variants) support reliable setup across common tooling blocks.

This punch blank is supplied in multiple steel options—PS, M2, and A2—so engineers can tune wear resistance and edge retention for different blanking/forming loads. The input data specifies that material is configurable by the selected variant.

• M2: high-speed steel commonly chosen when elevated wear resistance and cutting edge durability are required in high-cycle blanking.
• A2: an air-hardening tool steel variant often selected for strong toughness-to-wear balance depending on heat treatment.
• PS: used when a more practical tool steel choice is needed for forming/blanking with appropriate heat treatment to achieve the target hardness.

Heat treatment note: actual hardness (HRC) and specific heat-treatment condition are determined by the selected steel option and your in-house process. Typical tooling practice is to quench and temper for many tool steels and then grind/finish critical surfaces for dimensional accuracy; for high-wear applications, engineers may consider secondary treatments (e.g., nitriding) when compatible with the steel grade.

Correct selection starts by matching the punch blank’s shank diameter (D) and working length (L) to the die holder and punch guide dimensions. This series supports D = 4–32 mm and multiple L configurations: 40–100 mm, 50–100 mm, 56–100 mm, and 63–100 mm.

• Match D first: choose the largest D that fits your punch guide/bushing bore requirements while maintaining the intended clearance/fit. Keep in mind that punch shank assemblies typically require controlled clearance for smooth sliding and to avoid binding.
• Then match L: select an L range that provides enough length for retention, guidance, and access to your die set depth without interfering with neighboring components.
• Account for tolerance: design dimensions and finished punch geometry may differ from the blank due to machining, so plan for stock removal and grinding on critical surfaces.

Dimensions are primarily configurable by D and L within the listed ranges; confirm your station block geometry before final selection.
