Cutting Tools & Bits

Boring Bits and Cutting Tools from Surplus

Carbide-tipped hinge boring bits and shop tooling

Woodworking and machine shop tooling turns up regularly in the lots we buy, and this is where it lands. A recurring find is TCT hinge boring bits in left and right hand rotation, called out by cutting diameter, shank diameter, flute count, and overall length, which are the numbers that decide whether a bit fits the spindle you have. Since these are surplus, matched left and right pairs sometimes arrive together and sometimes do not. Photos show the actual cutting edges, so condition is visible before you order. Holders, collet chucks, and reducer sleeves for tooling like this are filed under workholding and toolholding.
