Parlec 10-12 Tapping Adapter Size 12 Numertap 100

Product Description

The PARLEC 10-#12 is a quick-change tapping adapter designed for use with Number 12 taps in CNC machining and production tapping applications. It belongs to the NUMERTAP 100 series and provides a secure, repeatable connection between the tap and the machine spindle. The adapter features a 0.22-inch tap shank diameter and a 0.165-inch tap square size, giving it a precise fit for standard Number 12 tap geometry. Licensed machinists and tooling technicians install this adapter in turret lathes, machining centers, and dedicated tapping machines where consistent thread quality and quick tool changes are required.

This adapter is suited for production environments running high-volume tapping cycles where tool change speed and repeatability directly affect throughput. The NUMERTAP 100 series is a recognized quick-change tapping system commonly used in vertical and horizontal machining centers. The 0.75-inch outside shank diameter and 1.18-inch flange diameter are compatible with NUMERTAP 100 series holders and tooling blocks. Coolant-through capability is not included in this adapter.

Key Features

• Quick-change interface for fast tap swaps without full tool disassembly
• Tap shank diameter of 0.22 inches fits Number 12 tap geometry precisely
• Tap square size of 0.165 inches ensures positive drive engagement
• 0.28-inch projection keeps the tap close to the holder for rigidity
• 1.18-inch flange diameter provides a stable, repeatable seating surface
• Part of the NUMERTAP 100 series for system-level tooling compatibility

Compatibility

Designed for use with Number 12 taps in the PARLEC NUMERTAP 100 quick-change tapping system. Compatible with NUMERTAP 100 series tapping holders and tooling setups using a 0.75-inch outside shank diameter.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the machine spindle is fully stopped and locked out before changing tapping adapters. Verify that the tap shank and square dimensions match the adapter specifications before seating the tap to avoid drive slippage or tap breakage. Follow the machine tool manufacturer guidelines for proper torque and retention when mounting the holder in the spindle.
