Inserts & Tool Bits

It represents a highly productive alternative to conventional turning where 80° & 35° corner inserts are fed in the same direction, and instead utilizes all 4 directions available on conventional 2 axis lathe (+Z, -Z, +X, -X) to maximize material removal.

With this new tool, V or D-style inserts with just two cutting edges and lower stability (ISO VBMT, VCMT, DCMT) are replaced with triangular cutting inserts with three cutting edges and high stability. These three-edged inserts allow for a 50° undercut angle, ideal for profiling operations.

To increase their use for steel turning applications across the automotive, energy and general engineering sectors, the upgrade includes more insert shapes for each grade. Having access to the correct insert shape is vital for effective finishing and roughing operations, and the insert shape should be selected relative to the entering angle accessibility required of the tool.

High tool life is achieved thru WEP10C coated cermet grade with multilayer TiCN TiAlN PVD coating and fine cermet micro grain.

The unique TiAlN-Al2O3 multilayer coating system makes the WSP45G both hard and tough, and thus extremely resistant to abrasive wear and high temperatures, with controlled residual stresses and less flank wear, all boosting tool life. A special mechanical post-treatment improves hairline crack performance and protects the cutting edge from micro-spalling.

Suitable for use on machines with limited power, the combination of new inserts and cutter delivers high metal removal rates with low cutting force and reduced chatter. It features positive axial and radial face angles for good cutting action and directing chips away from the work-piece.

The i-ONE line offers the advantage of a solid carbide drill combined with the flexibility of steel bodies. i-ONE micro-grain carbide inserts combine a new, multilayered H-coating and optimized cutting angles with tool steel holders with Torx Plus clamping stability. n

WBH20 is a grade well suited for ISO-H Group of material such as for hard turning applications. WBS10 is well suited for ISO-S materials, specifically nickel-based (such as Inconel), iron-based (such as Udimet) or cobalt-based (such as Hayens).

GC4415 and GC4425 are ideal for manufacturers operating in mass and batch production setups machining low-alloyed (P 2.1 to 2.6) and unalloyed (P 1.1 to 1.5) steels, respectively. Grade GC4425 has been shown to outperform competing inserts in a majority of steel turning applications.

Now, LACH DIAMOND doubles this efficiency by offering an insert with 2 tips: CBN-Duo-power.The development of new CBN cutting materials like the types B610 and B600 used by LACH DIAMOND met the demand of the automotive and component industry for a cutting material with long-term stability for the turning of hardened steels – and this with highest surface qualities of e.g.

The thick CrAlN coating provides high hardness and oxidation resistance solving issues related to machining materials such as: 304SS, 17-4PH, and Nitinol. High speed machining applications with ST4 inserts have proven results with stable machining, excellent surface finishes, and extended tool life.

Thanks to an impressive list of optimized features, the cutter generates exceptional tool performance across a broad range of applications and materials. A smooth cutting action and low cutting forces mean reduced power consumption and tool wear — tool life can actually be boosted by up to 130%.
