PTW Thin Wall Drill Bushings | ANSI Standard | Freer Tool & Supply

BH thin wall drill bushings in this collection are headless (straight) press‑fit drill bushings designed for jig and fixture drilling applications (application dependent; verify per listing). Thin‑wall drill bushings are commonly used when you need a space‑saving bushing—for example, when plate thickness is limited, when the available outside diameter is constrained, or when you want the largest possible usable inside diameter relative to the outside diameter (application dependent). The headless/straight style installs without a flange, which can help maintain a flush surface and simplify fixture layouts where a headed bushing won’t fit (application dependent).

Key Features

• Industry-leading thin wall design
• Precision-ground OD/ID with leads
• Heat-treated to 60-65 HRC
• Superior concentricity control
• ANSI PTW-Type standard compliance
• Made in ISO-certified facility

Headless Press Fit Thin Wall Drill Bushing – PTW

The Headless Press Fit Thin Wall Drill Bushing or ‘PTW Type’ has all the features of the ‘P Type’ bushing, but with the extra feature of a thin wall. Thin wall bushings are designated in preference to the P Type Headless Press Fit Drill Bushing when space on the jig is limited. Thin-wall drill bushings allow for closer hole spacing. The headless press fit drill bushing is pressed into the plate or fixture to achieve a flush surface. PTW Bushings are installed after a simple drilling and reaming operation.

Boneham drill bushings are precision ground on the outside and inside diameters with leads on the OD to prevent binding on installation. An entry point radius provides easy drill location. Counterbore or no counterbore options can be supplied.
