Tools & Gear Chasers Tangential Thread Cutting Chasers

PTANG3MM 3mm Pitch 1.3/64" x 4" Tangential Chasers 4 piece tangential thread cutting chasers - resharpenable. High Speed Steel, uncoated, chaser die set. Suitable for all Landis type tangential die heads. Tangential positioning with line contact at workpiece centreline gives natural cutting clearance and best tool performance. Dovetail clamping with back-up screw provides rigidity required to cut Acme and similar forms requiring heavy metal removal. Not necessary to regrind all chasers of set in equal amounts. Metal removed at regrind dependent upon condition of each chaser. A few thousandths metal removal at regrinding, usually .030" or less depending upon tool condition, restores the cutting edge. Chasers can be used to cut threads with any die head whose chaser holders are of the proper form and which accept that same size tool. Tool inventory is reduced since individual chaser sets do not need to be stocked for every diameter and pitch combination.
