Hertel K029163AS M16 X 1.50 Metric Fine Straight Flute Tap

Product Description

The HERTEL K029163AS is a straight-flute hand tap designed for cutting M16 x 1.50 metric fine internal threads. Built from high speed steel with a bright, uncoated finish, this plug-chamfer tap is suited for threading operations in ferrous and non-ferrous materials where a standard straight-flute geometry performs reliably. The left-hand thread direction requires deliberate tool selection, making this tap appropriate for reverse-thread applications. With a thread limit of D6 and four flutes, it provides consistent chip clearance and dimensional control across production and maintenance threading tasks. Overall length is 3-13/16 inches and the tap weighs 0.75 pounds.

This tap is used in machining and maintenance applications that require a left-hand metric fine thread. Typical scenarios include repair work on reverse-thread fastener locations, fixture building, and toolroom applications involving M16 left-hand threaded components. The plug chamfer style makes it appropriate as a through-hole tap or as the second step in a blind-hole tapping sequence following a taper tap. It is handled by machinists, tool and die makers, and maintenance technicians working with manual or CNC tapping equipment.

Key Features

• M16 x 1.50 metric fine thread form with left-hand thread direction for reverse-thread applications
• Plug chamfer provides approximately 3 to 5 leading threads for versatile through-hole and staged blind-hole use
• High speed steel construction offers a balance of toughness and wear resistance for general-purpose threading
• Bright, uncoated finish is compatible with a wide range of cutting fluids and workpiece materials
• D6 thread limit ensures consistent tolerance control on finished threads
• Four straight flutes support chip evacuation in short-chipping materials

Compatibility

Designed as an OEM-style straight-flute tap for M16 x 1.50 left-hand metric fine thread applications. No specific machine or equipment compatibility was provided by the manufacturer for this part number.

Installation Notes

This tap should be installed by qualified machinists or maintenance technicians familiar with hand and machine tapping procedures. Ensure the workpiece is securely fixtured and the tapping axis is aligned to the drilled hole before beginning the threading operation. Apply an appropriate cutting fluid for the workpiece material to reduce heat and extend tool life. Left-hand taps require counter-clockwise rotation for thread cutting, and operators should confirm spindle direction before engaging the tap in any powered tapping setup.
