ELK GROVE VILLAGE, IL—The redesigned BIG Daishowa Hi-Jet Holder, which provides coolant induction for machining centers without through-spindle coolant at speeds up to 10,000 RPM and pressures up to 290 PSI (20 bar), is now available from BIG Kaiser Precision Tooling Inc.

The Hi-Jet Holder improves hole making by forcing coolant through cutting tool coolant holes, allowing operations at faster speeds and feeds. It minimizes overheating and workpiece distortion, allowing cutting tools to provide faster metal removal by aiding chip evacuation during the machining process.

To meet increasing demand for high speed operations with carbide cutters, Hi-Jet Coolant Feed Holders are available in four different models with a .118" to 2.0" diameter range:

· New Baby Chuck Type – offers high precision suitable for small diameter drills, gun drills and endmills;

· Collet Chuck Type – accepts popular TG100 single angle-style collets;

· Side Lock Type – suitable for popular straight shanks by set screw clamping.

· KAISER KAB Type – improves boring and indexable drilling efficiency by adapting to all modular components of Kaiser tools.

The common shank tapers of BT40, BT50, CAT40 and CAT50 are all available with the four types and selection is based on cutting tool size, machine make and model. Their compact design and 360-degree adjustability assures compatibility with automatic tool changers, ensuring coolant delivery required for high speed cutting.

A unique design feature channels coolant through a separate sealing section, known as the Merit Set, directly into the center of the tool holder shank. This non-contact seal design prevents coolant from coming into contact with the bearings, thereby reducing wear and tear on the tool itself.

“Hi-Jet Holders are designed to introduce through-spindle coolant to machining centers that until now could not be used for coolant fed operations,” explained Chris Prystawsky, Assistant Product Manager, BIG Tooling Systems. “Small diameter cutters require high spindle speeds, as well as high coolant pressure due to the small diameter coolant holes. By having the coolant inducer and seals separated from the bearing assembly, users gain the advantage of high speed, high pressure cutting conditions without damaging the main body or bearings.”
