Accusize Industrial Tools 1″ x 6″ Turning Holder MTJNR-16-4D

Description

Product Overview

The Accusize MTJNR-16-4D turning holder is engineered for high‑precision machining on modern CNC lathes. Constructed from hardened steel, the holder provides a rigid platform that minimizes vibration and maximizes tool life. Its 1″ square shank offers a secure fit in standard collet chucks, while the 6″ overall length delivers ample reach for a variety of workpiece sizes. The integrated TNMG insert is designed with a negative 3º cutting edge angle and a negative rake, delivering efficient chip evacuation and reduced cutting forces. This combination of material quality, dimensional stability, and advanced insert geometry makes the holder suitable for demanding industrial applications such as facing, contouring, and profiling. Detailed specifications include a product dimension of 5.12 x 1.18 x 1.18 inches, a weight of 1.76 pounds, and compliance with ISO standards for indexable insert holders. The holder’s design reflects Accusize’s commitment to delivering reliable, high‑performance tooling solutions that meet the rigorous demands of precision manufacturing.

Usage

Designed for both small‑batch production and high‑volume manufacturing, this turning holder excels in environments where accuracy and repeatability are paramount. Machinists can employ the holder on a range of CNC lathe models, from entry‑level machines to advanced multi‑axis platforms. The holder’s negative rake geometry is particularly advantageous when machining tougher alloys such as stainless steel, titanium, and hardened tool steels, as it reduces cutting forces and extends insert life. Its versatility also supports a variety of cutting operations, including roughing passes, finish passes, and intricate contour work on complex geometries. The holder’s compact footprint allows it to be used in tight machine setups, making it ideal for aerospace component fabrication, automotive part production, and precision instrument manufacturing. Users benefit from quick insert changes thanks to the standardized TNMG insert size, which reduces downtime and enhances overall productivity.

FAQ

What types of materials can I machine with this holder?

The holder is suitable for machining a broad spectrum of materials, including carbon steel, stainless steel, aluminum alloys, titanium, and hardened tool steels. Its negative rake geometry helps reduce cutting forces, making it especially effective on tougher alloys.

Can I replace the TNMG insert with a different insert type?

Yes, the holder is compatible with any TNMG‑type insert that conforms to the standard dimensions. This flexibility allows you to select inserts based on specific cutting requirements, such as different edge geometries or coating types.

Is the holder compatible with all CNC lathe models?

The holder is designed to fit standard 1″ square shank collet chucks, which are common across most CNC lathe brands and models. Always verify the collet size and machine specifications to ensure optimal compatibility.

What warranty does Accusize provide for this product?

Accusize offers a one‑year limited warranty covering material defects and workmanship. Should any issues arise, our customer service team will assist with troubleshooting, replacement parts, or a full product exchange.

How do I maintain the holder for optimal performance?

Regularly inspect the shank and insert seating area for wear or debris. Clean the holder with a non‑abrasive solvent and a soft brush, and store it in a dry environment to prevent corrosion. Periodic re‑hardening is not required due to the high‑quality heat treatment applied during manufacturing.
