High-Carbon Steel Automatic Center Punch — Knurled Grip Precision Marking Tool
$50.35
Description
Good work starts with a good mark. This high-carbon steel automatic center punch delivers a clean, slip-free indent every time — no hammer required. The spring-loaded mechanism releases consistent force at the point of contact, while the knurled grip keeps your hand steady on metal, wood, and comparable surfaces. At 128 mm long and 12.7 mm wide, it sits naturally in the hand and slips easily into any tool roll.

Why This Punch
- High-carbon steel construction: Resists wear and maintains tip sharpness through repeated use on metal and wood surfaces.
- Spring-loaded precision: Delivers consistent impact force at the point of contact — no hammer, no guesswork, no slipping drill bit.
- Knurled grip design: Textured body gives confident control even in workshop conditions where hands may be dry or lightly oiled.
- Compact and portable: At 128 mm, it fits in any apron pocket or tool roll — ready wherever the work takes you.
- Clean indent, every time: The 2.0 mm tip creates a precise pilot mark that keeps drill bits seated from the first turn.
Care & Maintenance
- Cleaning: Wipe the body and tip with a dry or lightly oiled cloth after use to prevent surface oxidation.
- Avoid: Submerging in liquids or leaving in damp environments; moisture will accelerate corrosion of the carbon steel.
- Tip inspection: Check the punch tip periodically for wear or chipping; a blunted tip reduces marking accuracy.
- Spring mechanism: If the spring action becomes stiff or inconsistent, a small drop of light machine oil applied to the mechanism will restore function.
- Storage: Store in a dry toolbox or roll; avoid contact with other metal tools that may nick the tip.
FAQ
Does this require a hammer?
No — it's fully automatic and spring-loaded. Press the tip firmly against your workpiece and the internal spring releases a precise strike. No mallet or hammer needed.
What surfaces can it be used on?
Metal and wood are the primary surfaces. It is not suitable for hardened steel, tile, ceramic, or glass — use a carbide-tipped punch for those materials.
What is the punch point diameter?
The tip is 2.0 mm in diameter, creating a clean pilot indent sized for standard drill bits.
Is the strike force adjustable?
The spring mechanism delivers a consistent fixed force. This is a standard automatic punch — it does not have a user-adjustable tension setting.
Is this sold individually?
Yes — each order includes one automatic center punch. No additional accessories are included.
