Collis Tool 72451 MT2 Split Sleeve Tapping Driver Pipe Tap

Product Description

The COLLIS TOOL 72451 is an MT2 taper shank split sleeve tapping driver designed for pipe tap applications in machine tool setups. It accepts a 1/8 inch pipe tap with a 1 inch tap entry depth, a 0.437 inch tap shank diameter, and a 0.328 inch tap shank square. The 1/4 inch projection positions the tap correctly within the driver for consistent thread starting. This driver is used by machinists and tool-and-die professionals who need a secure, repeatable tap-holding solution on Morse Taper No. 2 spindles.

This tapping driver suits production and job shop environments where pipe threads are cut on drill presses, milling machines, or machining centers equipped with an MT2 spindle taper. The split sleeve design allows the driver to hold the tap shank securely while accommodating the standard square drive, making it a practical choice for through-hole and blind-hole pipe tapping operations in metal fabrication, plumbing component manufacturing, and HVAC fitting production.

Installation Notes

Installation is performed by machinists familiar with Morse Taper tooling. Power down and lock out the machine spindle before seating or removing the taper shank driver. Clean both the MT2 taper and the spindle bore before insertion to ensure full contact and prevent fretting. Follow the machine manufacturer guidelines and applicable shop safety procedures when setting tap depth and feed rate.
