• High-speed Steel (HSS) Broaches – Precision-ground, Hardened HSS Construction Delivers Excellent Edge Retention, Wear Resistance And Long Tool Life In Mild Steel, Aluminum, Brass And Non-ferrous Metals.
• ER-25 Collet Adapter For Rigid Mounting – ER-25 Adapter Ensures Tight, Low Run-out Tool Holding When Installed In Milling Machines, CNC Spindles, Drill Presses Or Tooling Fixtures.
• MT2 Morse Taper Shank Compatibility – Standard MT-2 Taper Shank Allows Secure Mounting In Lathes, Milling Machine Spindles, CNC Lathes, Manual Mills And Tooling Turrets.
• Precision Hex Rotary Broaching – Rotary Broaching Creates Accurate Internal Hex Holes In One Pass With Superior Surface Finish And Tighter Tolerances Compared To Conventional Broaching.
• ⚙️ This Rotary Broach Does Not Have The Wobble Feature; Therefore, Follow The Steps Mentioned Below For Effective Broaching.
• 📐 Offset The Tailstock By 1 To 1.5 Degrees For Proper Alignment During Broaching.
• 🛠️ Pre-drill Holes Larger Than The Broach Size: 10% Larger For Square Broaches And 3% Larger For Hex Broaches.
• 🌀 Alternatively, If Pre-drilling A Larger Hole Is Not Possible, Pre-drill The Hole To Match The Exact Size Of The Broach And Add A 45-degree Lead-in Chamfer. This Will Guide The Broach Smoothly Into The Workpiece And Ensure Effective Broaching.
