## Overview

The Starrett 18AA Automatic Centre Punch is a 4-inch, 7/16-inch diameter precision tool designed to create starter dimples without a hammer.

Its replaceable and sharpenable point, combined with an ergonomic knurled handle, makes it a must-have for professionals seeking reliable, hammer-free marking.

## Description

Product Description The Starrett 18AA automatic centre punch with adjustable stroke is 4" long with a 7/16" (11 mm) diameter for creating a starter dimple without the need for a hammer. The punch has an adjustable stroke, which can be set by turning the knurled cap and is regulated by spring tension for uniform dimple size at every setting. The punch is made from hardened and tempered steel components that provide wear resistance and strength. It has a round handle that is knurled for grip. The point can be removed for replacement or sharpening. Centre punches make small dimple marks in a workpiece to help guide a drill bit. Manual centre punches have a metal shank with a point and are typically tapped with a ball-peen hammer to mark the material. Automatic centre punches have an internal spring mechanism that enables them to mark the material without using a hammer, leaving one hand free for steadying the work. The L.S. Starrett Company manufactures precision measuring tools, metrology and testing equipment and saw blade products. Box Contains 1 x Automatic Centre Punch

Review: Auto centre punch - Item arrived as advertised and I’m very happy with it Thank you Good quality
Review: Excellent punch, strong recommendation from me. - As with other Starrett products, a well engineered punch. The "automatic" bit works just fine, leaving a significant mark in wood or steel. It is smaller than I expected (my prejudice?) but works perfectly well. Wholly recommended. I believe the tip is replaceable too - should it be needed
