The Metabo HPT 646083420 (WEF 15-150 Quick) 6 in. Flat-Head Angle Grinder is engineered for grinding, surface preparation, and cutting in tight spaces where standard angle grinders cannot fit. Powered by a 13.5 A motor with patented dust protection, this corded flat-head grinder features a low-profile gear housing and a rotatable design to access acute angles and restricted workpiece areas.

Built for metalworking professionals and fabricators, the grinder incorporates Tacho-Constamatic (TC) full-wave electronics to maintain constant speed under heavy load for fast, consistent material removal. User safety and control are prioritized with an integrated safety clutch and electronic safety shutdown that reduce kickback if the disc binds. Soft start, restart protection, and electronic overload protection further protect both the operator and the motor during demanding applications.

Efficiency is maximized through the tool-free Metabo Quick disc change system, which allows fast accessory swaps using a quick-locking nut without extra tools. A twist-proof, tool-free adjustable guard provides safe positioning, while the anti-vibration Metabo VibraTech (MVT) side handle reduces fatigue during extended use. Auto-stop carbon brushes safeguard the motor by shutting down the tool when brush wear reaches replacement thresholds.
