Grooving Tools

If you’ve ever struggled with inserts coming loose during a slotting operation, keep reading. How about inconsistent slot widths, fumbling with awkward screws and inserts on a slotting cutter, or having to use a piece of shim stock to pry wedged chips from deep inside a slotted workpiece? These are just a few of the problems machinists face when trying to cut narrow slots and grooves, but thanks to the newly introduced Kennametal Narrow Slotting (KNS) cutter, the days of “slotting dread” are over, according to the company.

The Pentacut HP Jet line from Iscar Metals Inc. combines the cost-effective Pentacut—which can be used in multifunction applications, including grooving, parting, recessing and chamfering—with innovative high-pressure coolant technology.

Tungaloy is enhancing TetraMini-Cut, one of the best of its grooving tool family, by adding a substantial number of new items to its TCG18 insert lines.

​​​In conventional lathe-type machine tools, the capability of feed motion in the XZ plane is an inherent limitation. In a parting operation, this inevitably directs the resultant vector of cutting forces sharply across the cross-section of the tool, resulting in high loads and susceptibility to deformation. The classical parting blade design compensates for this with a large height relative to the width. Sandvik Coromant engineers now have a remedy that utilizes the modern machines’ capability to feed the tool in the Y direction.

The new Walter Cut MX grooving and parting tool reportedly improves accuracy, stability and process reliability by adopting and improving on proven technology. These new indexable inserts have four cutting edges per insert.

Designed for internal threading and grooving applications, the new Carmex Modular Line (ML) uses a single boring bar that can be fitted with multiple adapters, offering high accuracy, easy adjustment and full repeatability. Coated with abrasive-resistant nickel, the ML adapters can be used with all Carmex standard thread turning inserts sizes 16, 22 and 27 mm.

Walter has unveiled the Walter Cut G1221-P, an innovative grooving boring bar with precision cooling, for recessing and internal grooving. This monoblock boring bar has two coolant holes.

Walter has introduced three new Walter Cut GX Tiger·tec Silver CVD grooving and parting grades—the WKP13S, WKP23S and WKP33S—for use on steel and cast-iron applications. These have been introduced in combination with Walter's geometries UD4, UA4, UF4, RD4 along with plunge grooving and parting geometries GD3 and CE4.

Tungaloy Corp. is broadening its TetraMini-Cut series grooving tool range for Swiss-type machines to include new insert lines, extending its grooving benefits with CNC lathes and turning centers. TetraMini-Cut features a compact four cornered insert that is securely clamped in an innovatively designed pocket for indexing repeatability and tool life stability.
