An automatic centre punch is a spring‑loaded hand tool used to make a permanent dimple or indent in a workpiece to mark drill centres and prevent drill bits from wandering. The Draper Tools Group D Automatic Centre Punch (DR13612) delivers repeatable centre marks without the need for a hammer, allowing one‑hand operation and accurate location of holes on metal, wood, plastics and composite materials.

This centre punch is manufactured from hardened carbon tool steel and features a hardened tip for long wear and edge retention. The tip is heat treated to a hardness suitable for marking common engineering materials while avoiding brittle failure; the body is tempered to withstand the forces from repeated spring compression. The external finish is a matt black oxide which gives basic corrosion resistance and reduces glare during use. The tool uses an internal coil spring mechanism rather than threads or an external drive; the head is a domed cap designed for thumb pressure and quick, ergonomic release.

Although hand punches are not governed by a single universal standard, this product is produced to meet recognised hand tool quality practices and general DIN/ISO/BS requirements for tool steels and hand‑tool safety. The spring mechanism is engineered for consistent impact energy and the tip geometry is compatible with typical centre‑drilling operations used in accordance with workshop standards.

Typical applications include marking drill start points in engineering workshops, setting out holes in sheet metal and fabrication, positioning for pilot holes in carpentry and joinery, maintenance and repair work in automotive and agricultural sectors, and general DIY. The automatic action is particularly useful in confined spaces, on vertical surfaces and when two‑handed hammering is impractical.

Key benefits are consistent, repeatable centre marks without the need for a hammer, a hardened tip that resists wear, a corrosion‑resistant finish and a compact, single‑handed design that improves accuracy and productivity. The tool’s construction ensures compatibility with standard drill sizes and pilot drills used for centre‑drilling operations.
