Collis Tool 71300 Split Sleeve Tapping Driver MT1

Product Description

The COLLIS TOOL 71300 is a split sleeve tapping driver designed for use with a Morse Taper 1 (MT1) spindle. It accepts taps ranging from size 0 to 6 and provides a tap entry depth of 23/32 inches. The driver uses a split sleeve mechanism to hold the tap shank securely while allowing the tap to float axially, which reduces the risk of tap breakage during through-hole and blind-hole tapping operations. A tap shank diameter of 0.141 inches and a tap shank square of 0.110 inches define the compatible tap geometry. Machinists and toolroom technicians typically install this driver in drill press or milling machine spindles equipped with an MT1 taper.

This tapping driver is suited for light-duty tapping applications on drill presses, milling machines, and similar machine tools with MT1 taper spindles. It is appropriate for use in production and job-shop environments where small-diameter tapping of sizes 0 through 6 is required. The 3/16 inch projection dimension positions the tap relative to the driver body to provide clearance for the workpiece. This tool is commonly used in metalworking, maintenance, and fabrication settings where consistent, low-breakage tapping of small taps is a priority.

Key Features

• Accepts tap sizes 0 through 6 for small-diameter tapping applications
• MT1 taper shank mounts directly into Morse Taper 1 spindles without adapters
• Split sleeve design allows axial float to reduce tap breakage
• Tap entry depth of 23/32 inches accommodates standard tap shank lengths
• Tap shank square of 0.110 inches provides positive drive engagement
• 3/16 inch projection for proper tap-to-workpiece clearance

Compatibility

Designed for use in machine tool spindles with a Morse Taper 1 (MT1) taper. Compatible with taps sized 0 through 6 having a 0.141 inch shank diameter and a 0.110 inch shank square.

Installation Notes

Installation is performed by a machinist or toolroom technician. Power to the machine tool must be locked out and tagged before inserting or removing the taper shank driver from the spindle. Clean both the MT1 taper shank and the spindle socket thoroughly before seating to ensure full contact and prevent fretting. Follow applicable machine tool safety standards and shop procedures when setting spindle speed for the tap size and material being threaded.
