Techniks 17130-1/2 End Mill Holder BT30 1/2 Inch Bore

Product Description

The TECHNIKS 17130-1/2 is a BT30 taper shank end mill holder designed for use in CNC machining centers that accept the BT30 spindle interface. It accepts a 1/2 inch bore and provides a 2.36 inch projection from the spindle face to the cutting tool, giving machinists a defined reach for toolpath clearance and workpiece access. The nose diameter measures 1-1/4 inches. With an overall length of 4.266 inches and a weight of 1.3 pounds, this holder is built for use in compact BT30 machining centers common in toolroom and light production environments. Installation is handled by CNC machinists and toolroom technicians.

This end mill holder is suited for vertical and horizontal CNC machining centers equipped with BT30 spindles. It is commonly used in toolroom machining, light production milling, and educational or prototype shops where BT30 tooling is the standard interface. The 2.36 inch projection makes it appropriate for operations where moderate tool reach is needed without sacrificing rigidity. No through-coolant capability is present, so external or flood coolant delivery is used when coolant is required during cutting operations.

Key Features

• BT30 taper shank for direct spindle mounting in BT30-equipped machining centers
• 1/2 inch bore accommodates standard 1/2 inch shank end mills
• 2.36 inch projection provides moderate tool reach for milling operations
• 1-1/4 inch nose diameter for stable clamping and tool support
• Overall length of 4.266 inches suits compact BT30 spindle configurations
• No through-coolant, compatible with external or flood coolant setups

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers equipped with a BT30 taper spindle interface and requiring a 1/2 inch bore end mill holder.

Installation Notes

Installation is performed by a CNC machinist or toolroom technician. Power down and lock out the machining center spindle before changing toolholders. Use the appropriate BT30 pull stud and torque the retention knob according to the machine manufacturer specifications. Inspect the taper shank and spindle bore for contamination or damage before seating the holder to ensure accurate tool runout.
