Parlec B40-10SC3 Collet Chuck BT40 Tg 1 Inch Through Coolant

Product Description

The PARLEC B40-10SC3 is a BT40 taper shank collet chuck designed for CNC machining centers that use TG PG100 single angle collets. It provides a clamping capacity range of 0.031 to 1 inch (0.79 to 25.4 mm) and delivers a TIR of 0.0002 inches for consistent concentricity across the cutting envelope. The 3-inch projection places the collet nose clear of workpiece features and fixtures, and the through-spindle coolant path directs fluid directly to the cutting zone. Machinists and toolroom technicians select this chuck for high-precision milling, drilling, and reaming operations where runout control and coolant delivery are critical.

The B40-10SC3 is suited for vertical and horizontal CNC machining centers equipped with BT40 spindles. Its TG PG100 single angle collet interface accommodates a broad range of round shank tooling within the 0.031 to 1 inch capacity window. The 3-inch projection is well matched to operations requiring clearance around part features or vise jaws. Through-spindle coolant compatibility makes this holder appropriate for high-speed and high-temperature applications where flood coolant alone is insufficient.

Key Features

• BT40 taper shank for direct mount in BT40 spindle machines
• TG PG100 single angle collet system with 0.031 to 1 inch clamping range
• 0.0002 inch TIR for high concentricity and reduced tool runout
• 3-inch projection for clearance in deep-pocket and fixtured setups
• Through-spindle coolant path for direct coolant delivery to the cutting edge
• 5.575 inch overall length and 2.440 inch nose diameter

Compatibility

Designed for use with TG PG100 single angle collets on CNC machining centers fitted with BT40 taper spindles.

Installation Notes

Installation and tool changes should be performed by a qualified machinist or toolroom technician with the spindle fully stopped and the machine in a safe, locked-out state. Use a proper BT40 tool holder tightening fixture and appropriate pull-stud torque specification from the machine builder before mounting. Verify coolant port alignment and confirm through-coolant passages are clear before running. Inspect collet and chuck bore for chips or damage each time tooling is changed.
