Description
Overview:
The Timco Cone Cutter 5-31 mm is a high-speed steel (HSS) step tool for precision drilling in thin sheet metal. It drills, enlarges, and de-burrs holes with a single bit, helping you work cleanly and efficiently. Built from durable HSS, it holds a sharp edge and resists wear when used with appropriate cutting lubricant. The wide 5-31 mm range covers common hole sizes for fixings, glands, and fittings, so you can reduce bit changes during a job. Designed for use in standard handheld cordless or corded drills as well as drill presses, it performs well on thin mild steel, aluminium, brass, and similar sheet materials up to 2 mm thick. A practical choice for trades and DIY, it gives smooth, round holes and tidy edges in one operation.
