Abbott Workholding HOW27M88A Soft Lathe Chuck Jaw Serrated

Product Description

The ABBOTT WORKHOLDING PRODUCTS HOW27M88A is a soft lathe chuck jaw with a serrated jaw interface, manufactured from 6061-T6 aluminum. It is designed for use in manual and CNC lathe applications where a machinable soft jaw is required for custom workholding setups. The serrated interface ensures a secure, repeatable connection to compatible chuck bodies. Measuring 4 inches in overall length, 2 inches in overall height, and 1.5 inches in overall width, this jaw delivers a compact, precise profile suited to close-tolerance turning operations. Machinists and toolroom technicians install these jaws when standard hard jaws do not provide the grip geometry or material compatibility required for the workpiece.

This soft jaw is applicable in production turning, toolroom, and job-shop environments where workpieces require custom-bored or contoured jaw faces. It is compatible with chuck bodies up to 8 inches in maximum chuck diameter. The 3-jaw set configuration supports concentric gripping of round or symmetric workpieces. The aluminum construction makes the jaw easy to bore and reface without damaging cutting tools, a common requirement when holding finished, delicate, or irregularly shaped parts.

Key Features

Installation Notes

Soft lathe chuck jaws are installed and bored by machinists or toolroom technicians. Before removing or installing chuck jaws, power down the lathe and confirm the spindle is fully stopped. Use the correct fastener size - 0.4724 inches - and torque fasteners evenly to prevent jaw distortion. After boring the jaw face to the required diameter, always run a test grip on scrap material before securing production workpieces.
