This Parallel Pin Punch 8 x 150mm is a cylindrical steel punch designed to drive out or align pins, dowels, roll pins and shafts with minimal enlargement of the hole. Its primary use is for removing parallel pins in assemblies where a straight, uniform punch face is required rather than a tapered drift, making it suitable for routine maintenance, dismantling and assembly tasks in mechanical workshops and on-site engineering.

The punch is manufactured from chrome‑vanadium tool steel in accordance with EN ISO 4957 tool‑steel specifications and is heat treated and tempered to provide a balance of hardness and toughness (approximately 48–55 HRC). The nominal diameter is 8mm with an overall length of 150mm; the shank is parallel throughout the working section to ensure accurate, centred impact on the pin. The working tip is machined square to the axis with a slight chamfer to aid initial location. The surface has a satin chrome finish that offers useful corrosion resistance and eases cleaning after use.

As a hand tool it has no thread, head or drive type — the punch is struck directly with a suitable hammer such as a nylon or ball‑pein hammer depending on the application. Because the steel is hardened to retain an edge on the tip, it is intended for driving out hardened steel pins; use of excessively hard striking tools should be avoided to reduce mushrooming and extend service life. The parallel form differs from tapered drifts and is chosen where bore size and pin alignment must be preserved.

Typical industries and applications include automotive repair and restoration, general engineering, machinery maintenance, agricultural equipment servicing, metal fabrication and joinery where dowels are used. The product is particularly useful for workshop engineers, fitters and maintenance technicians who require accurate, repeatable pin removal without enlarging bores.

Key benefits include a durable EN ISO 4957 tool‑steel construction for fatigue resistance, a corrosion‑resistant satin chrome finish, and a precise parallel diameter for compatibility with standard 8mm pins and holes. Duchy Fasteners stocks this item individually and in small packs and carries a broader range of pin punches across diameters and lengths to suit different workshop and site requirements.
