Tesa Brown Sharpe 598-291-500 Sine Bar 5.75 X 1 Inch

Product Description

The TESA BROWN SHARPE 598-291-500 is a precision sine bar used for accurate angular measurement and layout work in toolrooms, machine shops, and metrology environments. Measuring 5.75 inches long and 1 inch wide with a 5-inch roll center spacing, this sine bar delivers a center-to-center accuracy of 0.0003 inches and a parallelism of 0.0002 inches. Constructed from steel with a removable front stop, it is suited for demanding inspection and setup tasks. A back plate is included. Machinists, tool and die makers, and quality control technicians rely on this type of instrument for setting precise angles when used with gauge blocks on a surface plate.

This sine bar is intended for professional metrology and precision machining applications. It is well suited for use in toolroom environments where tight angular tolerances must be established or verified. The 5-inch roll spacing is a standard dimension that simplifies sine calculations when used with slip gauge stacks. The removable front stop adds versatility for holding workpieces during layout or inspection setups. This bar is appropriate for both one-off precision setups and repeat production inspection tasks in manufacturing environments.

Key Features

• Center-to-center accuracy of 0.0003 inches for reliable angular setups
• Parallelism of 0.0002 inches across the working surface
• Standard 5-inch roll spacing simplifies sine table calculations with gauge blocks
• Steel construction for durability in toolroom and inspection environments
• Removable front stop included for workpiece positioning during setup
• Back plate included for added support and mounting versatility

Compatibility

Designed as an OEM-style precision sine bar suitable for use with standard gauge block sets and surface plates in toolroom and metrology applications.

Installation Notes

Sine bars are used by machinists and metrologists on a clean, flat surface plate in conjunction with calibrated gauge blocks. Handle the lapped surfaces with care to avoid nicks or corrosion that would affect accuracy. Clean all contact surfaces before use and apply a light rust-preventive coating when storing. No power tools or electrical connections are required for use.
