Starrett 50271 Trammel Points 5 Inch Leg Forged Steel

Product Description

The STARRETT 50271 is a set of trammel points designed for layout and scribing work requiring precise arc and circle transfer. Each set includes two forged steel points with 5-inch legs and a wrinkle finish. Trammel points mount to a beam or bar, allowing the user to scribe large-diameter circles and transfer measurements that exceed the capacity of a standard compass or divider. The forged steel construction provides durability under shop and jobsite conditions. These points are suited for machinists, toolmakers, fabricators, and layout technicians who need reliable, repeatable scribing across large workpieces.

The STARRETT 50271 trammel points are intended for use in machine shops, fabrication shops, and precision layout applications. They mount to the Starrett 50B trammel beam and are well suited for layout tasks on metal, wood, and composite surfaces. The 5-inch leg length allows scribing of larger radii than standard compass-style tools, making them appropriate for both bench and floor-level layout work.

Key Features

• 5-inch leg length for large-radius scribing and layout work
• Forged steel construction for strength and long service life
• Wrinkle finish for improved grip and corrosion resistance
• Includes two points per set for immediate use
• Designed for use with the Starrett 50B trammel beam

Compatibility

Designed for use with the Starrett 50B trammel beam. Two points are included per set.

Installation Notes

Trammel points are installed by machinists or layout technicians and require no special tools beyond the compatible trammel beam. Secure each point firmly to the beam before scribing to prevent slipping during use. Inspect point tips for wear or damage before use, as dull or damaged tips reduce scribing accuracy.
