• MT3 Tang Style Precision Rotary Broach Holder – Robust Morse Taper MT3 Tang Style Rotary Broach Holder Engineered For Accurate Internal Square Broaching In CNC, Lathe, And Milling Operations.
• Metric HSS Square Broach Punch Set Included – Supplied With High-speed Steel (HSS) Metric Square Broach Punches For Producing Clean And Precise Internal Square Profiles In A Single Pass.
• Floating / Self-centering Broaching Design – Tang Style Rotary Broach Allows Smooth Cutting Action, Excellent Concentricity, Reduced Chatter, And Improved Surface Finish.
• 🛠 How to Use – Effective Broaching Guide 1️⃣ Understand the Tool Design ✔ Built-in offset (wobble) allows automatic centering, reducing tool wear and alignment errors.
• 2️⃣ Pre-Drill the Hole (Essential Step!) 🔹 Square Punches: Drill 10% larger than the punch size 🔹 Hex Punches: Drill 3% larger than the punch size
• 3️⃣ If Oversizing Isn’t Possible: Drill the hole exactly to the punch size Add a 45° lead-in chamfer to ease entry and improve finish
• 4️⃣ Use Lubrication 💧 Apply cutting oil during operation to reduce heat, enhance surface quality, and prolong tool life.
• 5️⃣ Start Broaching ⚙ Engage at appropriate speed – let the wobble action perform clean, accurate shaping of internal profiles.
