- Imperial HSS Hex Punch Set Included – Supplied With High-speed Steel (HSS) Hex Broach Punches (Imperial Sizes) For Clean And Precise Internal Hex Profiles In A Single Pass.
- Floating / Self-centering Broaching Action – Advanced Rotary Broaching Design Ensures Excellent Concentricity, Reduced Cutting Pressure, Minimal Chatter, And Superior Surface Finish.
- Wide Machine Compatibility – Ideal For CNC Machining Centers, Manual Lathes, Milling Machines, Drill Presses, And VMCs Using R8 Spindle Systems.
- Industrial-grade Construction – Precision-machined Hardened Alloy Steel Body With Quality Bearings For Vibration Control, Durability, And Long-term Reliability.
- 1️⃣ Advanced Self-Centering Wobble Mechanism – Enables controlled axial movement, ensuring smooth, precise, and chatter-free cutting for superior broaching results.
- 2️⃣ Optimal Pre-Drilling Guide – For best results, pre-drill holes slightly larger than the broach size: Square broaches require a 10% larger hole, while Hex broaches perform best with a 3% larger hole, ensuring smooth cutting and extended tool life.
- 3️⃣ Alternative Drilling Method – If pre-drilling a larger hole isn't feasible, drill to the exact broach size and incorporate a 45° lead-in chamfer. This reduces cutting resistance, enhances tool life, and ensures a smoother broaching process.
- 4️⃣ Apply Lubrication for Optimal Performance – Minimizes friction, dissipates heat, and enhances cutting efficiency, resulting in smoother operation, reduced tool wear, and extended tool life.
- 5️⃣ Precision Cutting Process – Reduces cutting resistance, enhances accuracy, and ensures a seamless broaching experience with clean and precise results.
