Product Description

The Guhring Ht 800 Wp Interchangeable Insert Drilling System Is Ideal For The Production Of Large, Highly-Accurate Holes In A Variety Of Materials For Wind And Water Power Stations, Engine Plants Or Gas And Steam Turbines. The Ht 800 Wp Drill Bodies Offer The Highest Accuracy And Rigidity. The Open Flute Geometry Combined With Internal Cooling Guarantees Optimal Chip Evacuation Across A Broad Range Of Hole Depths. The Reinforced Shank Ensures Strong And Accurate Clamping Of The Drill In The Tool Holder. Due To The H6 Shank Tolerance, The Drill Bodies Will Fit A Variety Of Tool Holder Options. The Hardened Tool Steel And Nickel-Plated Surface Treatment Utilized During The Manufacturing Process For The Drill Bodies, Combined With Incremental Body Sizes In Steps Of 0.5Mm Up To 31.99Mm Diameter And 1.0Mm Above 32.00Mm Diameter, Results In Optimal Wear Resistance On The Drill Bodies As Well. The Small Incremental Diameter Transitions Of The Drill Bodies Provide Additional Benefits Other Than Simply Reducing Wear On The Bodies. Due To The Improved Guidance And Stabilization From Margin Contact While Drilling, The Rigidity Is Also Increased, Resulting In Longer Tool Life And Improved Workpiece Finishes. The Optimized Flute Geometry Of The Drill Bodies Results In Outstanding Chip Evacuation Capabilities, Even While Drilling Deeper Holes. Optimal Cooling And Lubrication Is Applied Through Coolant Ducts Which Exit Into The Flutes And Directly Onto The Cutting Edge, Resulting In Longer Tool Life And Better Chip Evacuation. The Precise And Easily Accessible Insert Seat Allows The Insert To Be Changed While The Drill Remains In The Machine Spindle. Due To The Unique Clamping Design, The Insert Can Be Changed More Times Than With Competitors’ Systems Before The Body Needs To Be Replaced Due To Fatigue Of The Insert Seat.
