3 LT 800 WP drilling system ( 40 ) Until recently, the economical production of deep and especially large holes above 40 diameter with carbide tools was only achievable with the assistance of costly special solutions. The successful development LT 800 WP now provides a modular and theree costeffective solution this difficult area of machining. This amazingly up to diameter and a drilling depth up to 12 x D! The holder is equipped with coolant ducts, the interchangeable inserts are produced in ultra fine grade carbide. Further, important advantages: Optimal adaptability to every machining task due to the combination possibilities of different tool holders (i.e. HSK, ISO taper, VDI) with extensions, reductions and drill heads with interchangeable inserts. Powerful double cutting edge thanks to lightly modified LTT ISO indexable inserts with circular lands positioned in pairs. Simple replacement of the drill head and the interchangeable insert. Accurate spotting provided by interchangeable insert with special Ratio point geometry. Good support through the complete drilling depth thanks to double-sided lands. Last but not least: LT 800 WP is ideally suited as a core drill the enlarging of drilled holes. Also remarkable is the fact that, depending on diameter and material, holes up to 12 x D can be produced, i.e. gun drilling. LT 800 WP 1

26 LT 800 General Technical Inmation GUHRINGGUIDE Application recoendations through holes supporting lands of the outer indexable inserts must remain in permanent contact drilling depths in excess of 7xD centering is recoended with equal point angle of 140, or larger, to approximately 2/3 cutting edge diameter of the central interchangeable insert (do not apply standard centre drill to DIN332). If centering is impossible, spot-drill with reduced feed. interrupted cutting (cross holes, grooves, oblique entry/exit) is not recoended without prior tests. We recoend reducing the feed by approximately 50%. the standard LT800 tool system is also suitable drilling up to diameter 55.9 in stacked metal sheets. For drilling of stacked metal sheets above diameter 56, the standard cartridge must be replaced with a cartridge with a suitable indexable insert arrangement (see page 17). when replacing the central interchangeable insert (RT800), we recoend replacing the clamping screw with a new one (with clamping thread protection). with turning machines (vertical drilling tool) it must be ensured the tool operates precisely on centre. pre-requisite optimal machining results is a sufficient coolant supply (see diagrams page 22). The tool possesses only limited suitability dry machining or MQL. The cutting speed should be reduced by approxiamtely 30% whilst retaining the same feed rate. Safety recoendations: with rotating workpieces, a disc is created on hole break through. Due to the centrifugal effect there is a possible risk of accident! Safety precautions must be followed. in order to prevent damage to machine and tool, we recoend the prior determination of the required power and torque (see diagrams on page 22).
