SATA GL90751 Center Punch 4mm

Key specs include a 4mm hardened tip, forged high‑strength steel body, chrome-plated finish for corrosion resistance, heat treated for durability, and an ergonomic non‑slip grip for better control.

Securely clamp your workpiece, position the punch tip exactly on the intended mark, apply steady pressure, and give a light tap with a hammer to create a precise indentation. The hardened tip ensures a clean start for drilling.

Its high‑strength steel construction, hardened tip, and impact‑resistant design withstand frequent use. The chrome finish resists corrosion and the ergonomic grip provides better handling and reduces hand fatigue, contributing to safer operation.

Ideal for metalworking and woodworking projects that require accurate start points for drilling, milling, or machining. Its compact 4mm tip is great for precise, small-diameter work.

A 4mm tip offers a balance between precision and visibility, giving a clear indentation without being overly large. It’s well-suited for standard small-diameter drill points and detailed markings.

Compared to similar SATA punches on Fepy, the GL90751 with a 4mm tip sits between smaller 3mm and larger 5mm variants. For example, the 3mm version is more compact for very fine work, while the 5mm version marks larger points. See also these alternative SATA options on Fepy for side-by-side decisions:

Keep it clean and dry after use, wipe away residues, and occasionally apply a light coat of oil to the tip and metal surfaces to prevent rust. Store in a dry place to preserve the chrome finish and tip integrity.

Wear eye protection, secure the workpiece with clamps, keep fingers away from the impact area, and use controlled, steady taps rather than hard, rapid blows to avoid slips or tool damage.

The listing indicates a single-piece center punch crafted from forged steel with a chrome finish; it is sold as a standalone center punch (no additional accessories included).
