Description

Overview:
The Sealey HSS 4341 Step Drill Bit Set, Part No. AK4746, is a 3‐piece double‐flute set for clean, accurate hole-making across multiple diameters with a single bit. Manufactured from high‐speed steel (HSS 4341) for dependable wear resistance, each step drill covers a range of sizes, delivering a total of eighteen different hole options. The double straight flutes improve chip evacuation and help prevent clogging in thin materials. Supplied in a robust flip‐up metal case for organised storage and quick selection, the set suits cordless drills and corded pillar drills in the workshop or on site. Ideal for sheet metals, aluminium, brass, laminates, and plastics, the AK4746 offers a compact, efficient solution for tradespeople, maintenance teams, and DIY users who need versatile hole sizing without frequent bit changes.

Key Features:
