Each Chapman adapter bit is designed to be used within a specific torque range for that size. • Small bits are designed for less torque, large bits are designed for more torque.

Chapman adapter bits are tough, not brittle. • We use fine alloy steel that is heated treated and treated with black oxide to achieve a specific hardness, between Rc52 and Rc55 respective to the specific bit. Adapter bits that are too hard will shatter, bits that are too soft will twist.

Our smallest slotted bits, CM-88, CM-89, CM-90 are designed for use within a specific torque range. • Chapman tools are used by gunsmiths, machinists and hobbyists world wide to work on fine antique firearms, machines and equipment where marring or damaging a screw head would be disastrous. When using any insert bit, specifically the 88,89,90, if a screw is seated so tightly that the bit starts to bend -stop immediately- additional force may break the bit, rip off the screw head or worse yet marr the piece.

Our famous Chapman Midget Ratchet provides four times the torque of a large screw driver. • The ratchet provides excessive torque than small screws are designed for, so use gentle but even pressure to loosen small screws.

Some screws cannot be removed with a screwdriver. •Cross-threaded, burred, chipped, varnished screws or screws treated with Loctite (especially on firearms) are near impossible to remove without tapping into the screw or heat.
