• Single-pass Internal Hex Machining – Creates Clean, Accurate Internal Hex Holes In One Operation On CNC Lathes, Manual Lathes, Milling Machines & Drill Presses
• Self-centering Rotary Action – Teng-style Floating Broach Head Reduces Chatter, Improves Concentricity, And Ensures Consistent Hex Profiles
• Hardened Tool Steel Construction – Broach Punches Made From Heat-treated, Precision-ground Tool Steel For Long Life And Superior Wear Resistance
• 𝐄𝐟𝐟𝐞𝐜𝐭𝐢𝐯𝐞 𝐁𝐫𝐨𝐚𝐜𝐡𝐢𝐧𝐠 𝐈𝐧𝐬𝐭𝐫𝐮𝐜𝐭𝐢𝐨𝐧𝐬 1️⃣ Advanced Self-centering Wobble Mechanism – Enables Controlled Axial Movement, Ensuring Smooth, Precise, And Chatter-free Cutting For Superior Broaching Results.
• 2️⃣ 𝐎𝐩𝐭𝐢𝐦𝐢𝐳𝐞𝐝 𝐏𝐫𝐞-𝐃𝐫𝐢𝐥𝐥𝐢𝐧𝐠 𝐟𝐨𝐫 𝐏𝐫𝐞𝐜𝐢𝐬𝐢𝐨𝐧 – Achieve The Best Broaching Results By Pre-drilling Slightly Oversized Holes. For Square Broaches, Drill 10% Larger Than The Broach Size, And For Hex Broaches, Drill 3% Larger To Minimize Cutting Resistance, Enhance Accuracy, And Extend Tool Longevity.
• 3️⃣ 𝐀𝐥𝐭𝐞𝐫𝐧𝐚𝐭𝐢𝐯𝐞 𝐃𝐫𝐢𝐥𝐥𝐢𝐧𝐠 𝐌𝐞𝐭𝐡𝐨𝐝–if Oversizing The Pre-drilled Hole Isn't An Option, Match The Hole Diameter To The Broach Size And Add A 45° Lead-in Chamfer. This Minimizes Cutting Resistance, Enhances Tool Longevity, And Ensures A Seamless Broaching Operation.
• 4️⃣ 𝐀𝐩𝐩𝐥𝐲 𝐋𝐮𝐛𝐫𝐢𝐜𝐚𝐭𝐢𝐨𝐧 𝐟𝐨𝐫 𝐎𝐩𝐭𝐢𝐦𝐚𝐥 𝐏𝐞𝐫𝐟𝐨𝐫𝐦𝐚𝐧𝐜𝐞– Reduces Friction, Prevents Heat Buildup, And Enhances Cutting Precision. Proper Lubrication Ensures Smoother Operation, Minimizes Tool Wear, And Significantly Extends Tool Lifespan.
• 5️⃣𝐏𝐫𝐞𝐜𝐢𝐬𝐢𝐨𝐧 𝐂𝐮𝐭𝐭𝐢𝐧𝐠 𝐏𝐫𝐨𝐜𝐞𝐬𝐬 – Minimizes Cutting Resistance, Enhances Machining Accuracy, And Ensures A Seamless Broaching Experience With Clean, Precise, And High-quality Results.
