Overview
A spring loaded striker inside the body releases when you press the tip down, leaving a dimple that stops a drill bit from wandering. Twisting the cap adjusts the force, and the knurled steel body grips well with oily hands.
One handed marking is the reason to buy, freeing the other hand to hold the work. Tip hardness and replaceable tips are not described, so heavy daily use on hardened steel is unproven.
Who it's for
Home mechanics and woodworkers starting holes in metal or glass get precise dimples without a hammer. Production machinists marking hardened steel all day should choose a punch with stated tip specs.
Pros and cons
- One handed operation
- Adjustable striking force
- Two punches per pack
- Knurled anti-slip grip
- Tip hardness not listed
- Replacement tips not mentioned
- Size specs listed oddly
- Glass use needs care
Performance notes
Pressing the punch compresses an internal spring until it releases and drives the striker into the tip, so force stays consistent from mark to mark. Higher tension makes deeper dimples in metal, lower tension avoids cracking softer or brittle materials.
