Series Overview & Features

This comprehensive series covers a wide range of shank sizes, providing a solution for virtually any internal machining task on your CNC lathe.

• M-Type Clamp Mechanism: Offers superior clamping force and insert stability compared to screw-down styles. This design minimizes insert movement under heavy cutting loads, reducing vibration and extending tool life.
• Dedicated Right & Left Hand Models: The MWLNR series is for standard Right-Hand operations, while the MWLNL series is for Left-Hand operations, ensuring optimal chip evacuation and cutting geometry in any direction.
• Heavy-Duty Shank Sizes: Built to perform, with shank sizes ranging from 16mm (S16Q) up to 50mm (S50U), providing the rigidity needed for aggressive cuts in steel, stainless steel, and cast iron.
• Versatile Application: While ideal for internal grooving, these tools are also perfectly suited for internal profiling, threading, and face grooving operations with the appropriate insert.
• Precision Engineering: Manufactured to exacting tolerances for precise insert seating and repeatable performance, batch after batch.

Product Series Specifications

Select the correct tool holder based on your machine's tool holder capacity and the required reach for your internal features.

Note: The "08" in the model number typically refers to the size of the insert cutting edge length or the groove width it is designed for.

Applications & Technical Guidance

• Primary Work Materials: Carbon Steel, Alloy Steel, Stainless Steel, Ductile and Gray Cast Iron.
• Common Operations: Internal Grooving, O-Ring Grooves, Snap Ring Grooves, Internal Threading, Profiling, and Undercutting.
• How to Choose:
  1. Shank Size: Select the largest shank that can be comfortably accommodated by your machine's turret to maximize rigidity and minimize deflection.
  2. Hand of Cut (MWLNR vs. MWLNL): Choose based on the direction of the tool path. MWLNR (Right-Hand) is for standard operations where the tool moves from the tailstock towards the headstock. MWLNL (Left-Hand) is for the opposite direction.
  3. Insert Selection: These holders are designed for standard "G" type or similar internal grooving and profiling inserts. Select the insert grade and geometry based on your material and operation.

Why Choose BEYOND MWLNR/MWLNL Boring Bars?

• Unmatched Clamping Security: The M-type clamp is renowned for its strength, making it the preferred choice for intermittent cuts and high-feed operations.
• Reduced Vibration & Chatter: The solid construction and secure clamping directly translate to smoother cuts and better surface finishes.
• Industry-Standard Compatibility: Uses widely available ISO-standard inserts, keeping your tooling costs low and inventory simple.
• Proven Durability: Made from high-grade materials and heat-treated for long-term reliability in a production environment.
