Starrett BI Metal Cordless Smooth Cutting Holesaws (CSC Holesaws) are constructed of hardened heat and abrasion resisting high speed steel teeth with a tough alloy body and cap, giving exceptional strength, durability and shatter resistance. Designed for use with battery operated power tools, our CSC Holesaws will cut twice as many holes as the equivalent standard holesaw per battery charge.

Advantages:

The perfect tool for onsite work with battery operated power tools.
Ideal for cutting stainless, tool and mild steel sheeting plus plasterboard, wood and thin plastics
Complete assembly - there is no requirement to purchase a separate arbor and pilot drill.
Constant pitch teeth provide exceptionally smooth cuts. Pitch 8 teeth per 25mm/inch.
Safety stop at the base of the holesaw prevents drilling beyond maximum cutting depth.
