Overview of Broach Cutters and Jetbroach Cutters

This document provides detailed technical specifications, part numbers, and operational recommendations for various broach cutters, including Jetbroach and Hi-Broach types, used in industrial machining for hole cutting.

1. Product Specifications and Part Numbers

• Broach cutters are available in a wide range of diameters from 12 mm up to 100 mm and beyond, with corresponding part numbers (PN) listed for each size.
• Depths of cut vary by model and diameter, typically ranging from 25 mm to 75 mm, with some specialized cutters designed for stacked plates.
• Shank types include 4 Morse taper shanks, with optional attachments for continuous and adjustable cutting oil flow.
• Specific part numbers are assigned to each diameter and depth combination, facilitating precise ordering and inventory management.

2. Cutter Types and Features

• Broach Cutters: Superior to twist drills for machining difficult materials, providing faster and better-finished holes.
• Jetbroach Cutters: Include one-touch and side-lock types, designed for ease of use and quick tool changes.
• Hi-Broach Cutters: Designed for larger diameters and deeper cuts, with pilot pins to ensure accurate hole location and automatic slug ejection.
• Spring-loaded pilot pins are standard, enabling quick hole location and automatic slug ejection at the end of the cut.

3. Operational Recommendations

• Test drilling with small size cutters is recommended to determine machinability of difficult materials and minimize trial costs.
• Use of cutting oil is advised, with optional attachments available to provide continuous and adjustable oil flow to the cutting area.
• Broach cutters are suitable for stacked plates, with specific models designed for this application.

4. Dimensions and Technical Parameters

• Diameter ranges are specified for each cutter type, e.g., 12-17 mm, 17.5-35 mm, 17.5-52 mm, and up to 100 mm.
• Depths of cut vary, with common depths including 25 mm, 35 mm, 50 mm, 65 mm, 75 mm, and 100 mm depending on cutter size and application.
• Shank diameters and pilot pin sizes are detailed, typically ranging from 5 mm to 8 mm.

5. Summary of Advantages

• Broach cutters provide faster, cleaner holes compared to twist drills.
• Spring-loaded pilot pins improve accuracy and efficiency.
• Optional oil flow attachments enhance cutting performance and tool life.
• Wide range of sizes and depths available to suit various industrial applications.

This document serves as a comprehensive reference for selecting and ordering broach cutters and related accessories, ensuring optimal machining performance and cost efficiency.
