Lathe Sleeves
Precision Lathe Boring Bar Sleeves: Rigid Support for Superior Finishes
Product Overview
Achieve ultimate rigidity, minimize vibration, and unlock the full potential of your boring bars with our premium lathe boring bar sleeves. These precision-engineered adapters securely hold round-shank boring bars, transforming your standard tool post into a high-performance boring system. Perfect for deep hole boring, internal turning, and achieving exceptional surface finishes where deflection is the enemy.
Key Features & Benefits
Eliminate Deflection & Chatter: Our thick-walled, heat-treated steel sleeves provide maximum support along the entire bar length, dramatically increasing rigidity for smoother cuts, better accuracy, and improved tool life.
Universal Compatibility: Instantly adapt round-shank boring bars (common in modern carbide insert systems) to fit square or rectangular tool posts. No need for expensive, dedicated boring tool holders.
Precision Ground for Perfect Alignment: Sleeves are precision ground on all critical surfaces (O.D. and bore) to ensure concentricity and parallel alignment with the lathe axis, guaranteeing accurate bore geometry.
Secure Locking Design: Features a robust sidelock clamping screw (or set screws) that exerts powerful, even pressure to lock the boring bar without causing distortion or slippage, even under heavy cuts.
Cost-Effective Tooling Solution: Expand your boring capabilities without purchasing multiple dedicated holders. One quality sleeve accommodates an entire range of round shank bars of the same diameter.
Heavy-Duty Construction: Made from high-grade alloy steel, hardened and ground for wear resistance and long-term durability in demanding workshop environments.

How to Choose the Right Sleeve:
Measure Your Tool Post: Determine the exact size (e.g., 1" square) of the opening in your quick-change or lantern tool post.
Measure Your Boring Bars: Identify the shank diameter of the round boring bars you need to support.
Select the Sleeve: Choose the sleeve where the outer shank size matches your tool post and the inner bore size matches your boring bar.
Ideal For:
Machinists & Toolmakers needing reliable, rigid boring setups.
Maintenance & Repair Shops performing occasional boring operations.
Hobbyists & Model Engineers upgrading their lathe tooling for better results.
Job Shops looking for flexible, space-saving tooling solutions.
Applications: Deep hole boring, internal grooving, finishing bores to tight tolerances, and any operation where bar vibration leads to poor surface finish or tool failure.
