The Paprsky Thread Scale Centre Gauge – 55° is a stainless-steel precision tool designed for lathe threading operations. It is used to check and set the angle of single-point screw-cutting tools, align threading tools perpendicular to the workpiece, and provide reference scales for common thread pitches. Designed for Whitworth 55° thread forms, the gauge supports accurate tool grinding, positioning, and thread verification. Its compact format makes it a practical tool for machinists, maintenance personnel, workshops, and training applications where reliable thread-cutting setup is required.
Paprsky offers practical precision tools designed to support consistent setup and dimensional checking in machining, fabrication, and maintenance environments. The Thread Scale Centre Gauge – 55° provides a compact stainless-steel reference for Whitworth thread-tool grinding, alignment, angle checking, and pitch identification.

Key Features
- 55° Whitworth Thread Reference: Designed for checking and setting tools for 55° thread forms.
- Thread-Pitch Scale: Includes reference scales for 14, 20, 24, and 32 threads per inch.
- Single-Point Tool Setup: Supports setting and checking the angle of single-point screw-cutting tools.
- Threading-Tool Alignment: Helps align the threading tool perpendicular to the workpiece before cutting.
- Tool-Grinding Support: Provides a reference for grinding the tool to the required thread angle.
Usage Instructions
- Confirm that the intended thread form requires a 55° Whitworth thread angle.
- Select the relevant gauge reference according to the required thread pitch.
- Use the 55° profile of the gauge to check or grind the single-point threading tool to the correct angle.
- Place the gauge against the workpiece and align the threading tool perpendicular to the workpiece axis.
- Use the thread scale as a reference for the required pitch.
- Recheck the tool angle and alignment before beginning the threading operation.
Applications
- Lathe Operations: Setting up tools for accurate screw-cutting operations.
- Machining Workshops: Checking thread-tool angles and alignment during machining work.
- Aerospace and Automotive: Supporting thread-profile verification and cutting-tool alignment.
- Tool Grinding: Providing a reference when grinding single-point threading tools.
- Technical Training: Teaching threading-tool positioning, thread angles, and pitch identification.
- General Maintenance: Supporting thread-related inspection and tool-setting tasks.
