Assorts Straight Shank Rotary Broaching Live Center Set with 7 HSS HEX Punches (3mm–12mm) – Precision Lathe Tooling Kit

The Assorts Straight Shank Rotary Broaching Live Center Set With 7 HSS Hex Punches (3 mm–12 mm) Is A Precision Lathe Tooling Kit Designed For Professional Metalworking And High-accuracy Internal Hex Broaching. This Comprehensive Set Features Seven High-speed Steel (HSS) Hex Punches Ranging From 3 mm To 12 mm, Covering The Most Commonly Used Hex Sizes For Fast And Efficient Production. Featuring A Robust Straight Shank Live Broach Holder, This Set Ensures Secure Alignment For Rotary Broaching And Wobble Broaching Operations On Both CNC And Manual Turning Machines, Lathes, And Tailstocks. The Hss Construction Delivers Enhanced Cutting Edge Strength And Wear Resistance To Tackle Hex Broaching Tasks In Steel, Aluminum, Brass And Various Machinable Materials, Supporting Long Tool Life And Consistent Performance. Rotary Broaching (Also Known As Wobble Broaching) Creates Accurate Polygonal Forms By Feeding The Broach Into A Pre-drilled Hole While The Workpiece Rotates With The Tool Held At A Slight Angle — Producing Clean Internal Hex Profiles In A Single Pass Without Excessive Forces. This Live Center Broaching Set Is Ideal For Shops And Job Environments Producing Internal Hex Features For Fasteners, Connectors, Sockets, Keyways And Precision Components. Easy To Set Up, Versatile In Application, And Engineered For Repeatable Results, It Is A Must-have Accessory For Machinists And Metal Fabricators Focused On Efficiency And Accuracy.

• Versatile Machining Compatibility – Works With Bench Lathes, CNC Turning Centers, Manual Machines, Drill Presses And Tooling Holders For Best Adaptability In Shops Of All Sizes.
• ⚙️ 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.
