This deburring multi tool includes a straight blade, two curved blades and a countersink. The straight blade and curved blade are forged from high carbon chromium steel for extreme wear resistance, perfect for deburring a wide range of materials and can be used for tool and die work, or even deburring a vehicle brake pipe after forming a new flare. There is also an HSS curved blade, designed for use on brass, cast iron and stainless steel. The 90° countersink can chamfer holes from 1mm to 10.4mm diameter and is on a cranked quick-change shaft for ease and speed of use. The tool handle is rubber-faced for grip and comfort and each blade locks positively in position when in use. Ideal for plumbers, mechanics and machinists who require quick access to various deburring tools.
