Parlec C40-16ERP262 ER16 Collet Chuck CAT40 Taper

Product Description

The PARLEC C40-16ERP262 is an ER16 collet chuck designed for use with CAT40 taper spindles in CNC machining centers. It accepts ER16 collets with a clamping range of 0.51 mm to 9.98 mm (0.020 inches to 0.393 inches), making it suitable for a wide range of small-diameter tooling including drills, end mills, and reamers. The chuck features a 2.62-inch projection from gauge line and a total indicator runout (TIR) of 0.0002 inches, supporting precision work where concentricity directly affects surface finish and tool life. Through-spindle coolant capability is built in, directing fluid to the cutting zone for improved chip evacuation and thermal management. Installed by CNC machinists and toolroom technicians.

This collet chuck is suited for production and toolroom environments running CAT40-spindle machining centers. It is commonly applied in operations requiring consistent runout control on small-diameter tooling, such as precision drilling, light milling, and reaming in ferrous and non-ferrous materials. The ER16 collet series is a widely standardized system, and this chuck is compatible with any ER16 collet meeting DIN 6499 or equivalent dimensional standards within the stated capacity range.

Key Features

• ER16 collet system with clamping capacity from 0.51 mm to 9.98 mm (0.020 to 0.393 inches)
• CAT40 taper shank for direct mounting in CAT40 spindles without adapters
• 0.0002-inch TIR for tight concentricity control on precision tooling applications
• 2.62-inch projection from gauge line for reach into workpiece features
• Through-spindle coolant passage directs coolant to the cutting edge
• Nose diameter of 1.110 inches with an overall length of 5.307 inches

Compatibility

Compatible with standard ER16 collets within the 0.51 mm to 9.98 mm capacity range. Designed for use in CAT40-spindle CNC machining centers.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician. Clean the CAT40 taper and spindle bore thoroughly before mounting to ensure full contact and accurate runout. Torque the retention knob or drawbar according to the machine tool manufacturer specification, not the chuck manufacturer, as values vary by machine. Verify TIR with a dial test indicator after installation before beginning any precision operation.
