Tungsten carbide burrs offer a means of de-burring, shaping and chamferring inside recesses using die grinders. We offer a range of shapes to facilitate different tasks. We also offer 2 grades to suit different metals. Most are 'Hard Metal' grade, ideal for steel, stainless steel and hard alloys. There is also a smaller selection of 'Non-Ferrous' grade which are better for bronze, aluminium alloys and brass. They are also effective on wood and can be a useful aid to carving.
Drive Tools:
Die Grinders: Most of our selection has 6mm spindles to suit the most popular collet size in die-grinders.
Dremmels: There is a small selection available with 3mm spindles. These will suit Dremmels and other detail and hobby tools.
Larger: We offer a small number of burrs with 8mm spindles. These will mainly suit drill chucks.
Extended Spindle: We offer an extended spindle (169mm) option on ball ended burrs.
Recommended Cutting Speeds: These products will work effectively through a wide speed range, but for more specific guidance, please click the 'More Information' Tab.
