Schlitter Tool Inc. - We Tool Your World

Schlitter Tool has over 6,000 original tool designs and holds numerous patents.

Schlitter Tool Inc. shave tool holder

The floating pin-style shave tool holder introduced by Schlitter Tool nearly  70 years ago still remains the best selling shave tool holder for screw machines. However, the original pin style floating mechanism has limited ability in countering the machining conditions that may induce "chatter". While skilled operators have developed some makeshift fixes to reduce chatter, none has proven to be reliable and some may even reduce chatter at the expense of accuracy.

For this reason, Schlitter Tool has introduced the patent pending "Ultimate G Style" shaving system that fights chatter and provides the user with more advanced options in tooling selection. The shave tool holder has a dovetail float mechanism that features a hardened and ground dovetail slide with a tapered gib. This dovetail float mechanism has from eight to ten times the bearing surface of the original pin style holders which actively fights chatter while providing a smooth floating action over the part. The gib is adjustable with a single screw and cannot be misaligned.

A key feature on the new "G Style" shaving system is the replaceable tool post. The tool post can be removed without having to remove the shave tool holder or altering the setup at the machine. The tool posts are available for standard dovetail tools or for more advanced HSS and super carbide insert type tools.

One user is reporting that they have used a new Schlitter "G Style" shave holder with carbide inserts on a part that has always showed chatter and found that the chatter marks have been completely eliminated and the surface finish improved from 45Ra to 9Ra. Tool life was improved from 6,000 pieces per edge to over 60,000 pieces per edge. The user also reports that no adjustments to the shave tool holder have been required on the machine that has been running two shifts-a-day for over three months.     

The new "G Style" shave tool holders use standard replacement parts, offsets, adjustments and adapter blocks and are available in seven capacities from 0 to 2-1/4 inches. New designs specifically for Davenport machines will be available with the year.

Schlitter provides complete design and manufacture for dovetail cutting tools as well as the special pre-formed rectangular and triangular cutting tool inserts that can be used in shaving or forming. The inserts are produced from specially engineered super carbide and super high-speed-steel engineered for maximum performance on screw machines. 

ISMS sells a variety of tool holders for Davenports, standard screw machines, and CNCs.
