Products Description

This MTJNR L Tool Holder is built with a lever-type clamping design that actually holds the insert where you put it. Force distributes evenly across the insert face, so the clamping stays reliable throughout the cut. No loosening, no displacement-just stable cutting that keeps your dimensions accurate and your scrap rate down. Whether you're roughing out material, taking semi-finish passes, or dialing in that final finish bore, this holder handles internal machining without the headaches.

The boring bar body is high-quality alloy tool steel, heat-treated and quenched to spec. It's got the hardness to resist wear and the toughness to take the shocks that come with internal work. The anti-vibration groove design is what sets this Internal Lathe Tool Holder apart-it actively suppresses the chatter that destroys surface finish and burns up inserts when you're boring deep. Your parts come out smoother, your tools last longer, and you spend less time fighting harmonic vibration that makes good cuts impossible.

The MTJNR L Internal Turning Tool delivers stable internal turning performance with optimized tool design for precision boring. It is widely used in CNC machining for achieving accurate internal profiles.

This holder takes standard VNMG series rhombic inserts. You can swap in different substrates and coatings depending on what you're cutting-carbon steel, stainless, cast iron, whatever comes through the door. This Internal Turning Tool Holder approach means one bar covers multiple applications. You're not locked into a single-purpose tool. Adapt to the job with insert changes, and your tooling budget goes further.

The 93° lead angle is the right geometry for internal work. Low radial cutting force means less deflection when the bar is extended, and the design provides natural vibration resistance. Internal boring, face turning at the bottom of a bore, stepped holes-this MTJNR Lathe Holder covers the range. It's the kind of general-purpose internal tool you want in the turret when you're not sure what the next job will bring.

Surface treatment is black oxide anti-rust finish. That matters in a real shop environment where humidity and cutting oil create corrosion problems. This holder won't turn into a rusted mess sitting in the tool crib. Even after months between jobs, it comes out ready to work without pitting or surface damage.

Size range covers what you actually need: S20R, S25S, S32T, and other standard shank sizes. Fits different CNC lathe models and turret configurations without hunting for special adapters. Installation is straightforward, positioning is accurate, and you spend less time dealing with setup errors and more time making good parts.

The economics work in your favor. Indexable insert design means when the cutting edge wears out, you pop in a new insert and keep cutting. The holder stays in the machine. You don't throw away money replacing whole boring bars, and your consumable costs drop significantly over time. For internal machining operations, this is the kind of practical tooling that keeps a shop running profitably.
