We are Manufacturing the chaser suit for Lanco, Landies, Landmatic, Landex, Kandal & Gents, Heap Die Head, Wagner, Redilmatic Die Head and also manufacture as per Costumer’s requirement as per drawns or sample. throat, ability to work, close to a shoulder throughout the life of the chaser and easily altered ss the entire width of the die or when used with lead screw feed. cutting angle to suit different material Tangential chasers have a self guiding action, except when ground across the entire width of the die or when used with lead screw feed.

REGRINGDING : When dull these chasers are reground onl on the cutting edge and never on is completely renewed at each regaining so the same results can be obtained from reground.

DIAMETER THREADED : One set of chases can be used to thread different diameters of the same pitch, provided the helix angle gree above or below for standard thread forms. For accurate work the variation in the lead angle should not be overlooked. fo the thread being cut and that of the chasers-holder do not vary more than half a degree above or below for standard thread forms. For accurate work the variation in the lead angle should not be overlooked.

LEFT HAND THREADING : The same chasers can be used for left hand and right hand threads. For left-hand threads the chasers are ground on the end opposite to that for right-hand threads. Left-hand chaser holders are required for left-hand work and the chaser must be inserted in numerical order, but anticlockwise when facing the diehead. The machine must be reversed for left-hand work.

MARKING ON CHASERS : Each STI tengential chasers is marked. The diameter is not usually marked because the same chaser may be used for threading different diameters.

TYPES TO SUIT VARIOUS MATERIALS : This is determind by the cutting edge, known as the Rake Angle, which varies according to the nature of the material to be threaded, its machinability, the thread to be cut and the method of feeding the work into the diehead. The following are given as a given as a guide, but Rake Angles should be finally determined by the experiment.

THROATS : STI tangential chasers are supplied with one of five standard throats that are 1) 45° (no throat, 3) Standard short throat 20°, 4)Long throat 15°, 5) Extra Long Throat 12°.
