Starrett PT06690 Replacement Point

The Starrett PT06690 is a contractor-grade replacement point crafted from steel. It is designed for technicians and tradespeople who need a durable spare for their Starrett 18A automatic center punch. This component restores the tool's original marking function without requiring a full replacement.

Thermals noise and power draw

As a passive steel component, the replacement point generates no heat and produces no audible noise during operation. It requires no electrical power and adds negligible mass to the punch mechanism. Performance depends entirely on the manual force applied by the user.

Build quality and mounting

The hardened steel construction resists deformation under repeated impact use. It threads directly into the Starrett 18A body for a secure fit that prevents loosening during operation. The precise machining ensures consistent alignment for accurate center marks on metal workpieces. Workers needing impact-rated tips or compatibility with other punch models cannot use this part.

Questions about this item

How do I install the PT06690 replacement point on the 18A automatic center punch, and what step is often missed?

Unscrew the old point from the 18A body, thread the PT06690 steel point in until it seats fully, then tighten the lock nut so the point cannot rotate during impact.

What maintenance or replacement will the PT06690 steel point need after extended use?

Inspect the tip for mushrooming or blunting; replace the point when the tip radius no longer marks cleanly, as the contractor-grade steel cannot be re-sharpened to original geometry.

What limit appears first when the PT06690 is used repeatedly on hard materials?

The tip deforms before the tool body, so marking accuracy is lost once the steel point mushrooms, requiring a new PT06690 point to restore clean impressions.
