Precision Center Punch Set

The Mitutoyo 985-138 is a five-piece set of steel center punches finished in black oxide for corrosion resistance. The tools measure 3 and 4 inches in length and are supplied in a storage pouch. They are intended for machinists and metalworkers who need accurate starter marks before drilling.

Who benefits and who does not

This set suits professionals and serious hobbyists performing layout work on metal where precise dimple placement matters. The limited selection of two lengths will not cover jobs requiring very small, very large, or intermediate punch diameters. Buyers needing automatic spring-loaded operation or replaceable tips should look elsewhere.

Deciding specification

The set contains exactly five punches in only two straight wireway lengths: 3 inches and 4 inches. Confirm that these two sizes match the hole locations and material thicknesses you typically work with before purchasing.

Questions about this item

Will the 985-138 punches mark starting points on workpieces already clamped in a mill or drill press?

Yes, the 3-inch and 4-inch straight wireway lengths let you reach into typical machine setups to create accurate centre marks before drilling.

How can I verify each punch is aligned and striking true after unpacking?

Tap each punch lightly on a scrap piece of steel; a clean, centred dimple with no skidding shows the tip is square and the black-oxide finish is intact.

Does the 5-piece set include the storage pouch, or must I buy one separately?

The pouch is included in the box, so no separate purchase is needed for storage.
