2 CoroDrill 808 First choice for close tolerance deep holes We have followed the industry closely for many years, listening to your challenges, needs, and requests when it comes to deep hole drilling and applications that require close tolerances. Based on these findings, our research and development team has designed a drill perfectly suited for the energy segment. One example is heat exchanger plates, where difficult materials such as low carbon steel, clad with Inconel, means poor chip breaking, short tool life and time consuming maintenance. The new generation CoroDrill 808 handles even the toughest conditions. Read on to find out how.

3 CoroDrill when tolerance matters If you are machining holes with diameters between and mm ( inch) and have close hole tolerance demands (IT9), CoroDrill 808 will get the job done. It performs well in the toughest of materials such as zirconium-alloyed materials, Inconel, and low carbon steels. CoroDrill 808 produces high quality holes in depths up to 150 times the diameter. This drill is commonly used for those components that require close tolerances such as heat exchanger plates in the energy industry, axles and engine blocks for automotive, and for primary metals. The CoroDrill 808 does not require any pre-settings. Benefits Predictable tool life and robust design gives it high process security Optimized cutting edge geometry provides excellent chip breaking Close tolerance of gauge bands on shank gives it high accuracy Optional dot matrix code available for full traceability Large stocked assortment means it is readily available

4 Performance CoroDrill 808 saved both time and money for a manufacturer of heat exchanger plates Looking for a more cost-efficient deep hole machining solution, this manufacturer turned to Sandvik Coromant. Switching from an older drill to the CoroDrill 808 gave incredible results: % 16% hours saved in production time per year productivity increase in recommended tool life productivity increase in total cycle time Component Workpiece material Straightness, mm (inch) Heat exchanger plate SA 266M (low carbon steel) 0.1 mm ( inch) Drill diameter, mm (inch) /-0.05 ( /-0.002) Guide Bush Coolant pressure /-0.01 mm ( / inch) 55 bar (798 PSI) Cutting data CoroDrill 808 Competitor v c m/min (ft/min) 80 (263) ( ) f n mm/rev (inch/rev) (0.006) ( ) v f mm/min (inch/min) 206 (8.110) ( ) Tool life, min

5 Our premium drills are equipped with a dot matrix code which contains a measurement protocol reference. Did you know? Sandvik Machining Technology develops the advanced materials available for the energy industry which are the same materials commonly machined with CoroDrill 808. Sanicro is one such material. It is an austenitic nickel-chromium-iron alloy commonly used in steam generators in nuclear power plants. This material is highly corrosion resistant in caustic environments and has excellent performance in nitric acid solutions which is a challenging material to machine. CoroDrill 808 provides close tolerance holes.

6 CoroDrill 808 first choice for close tolerance deep holes CoroDrill 808 somewhat overlaps with our indexable offer. For cost efficiency an indexable drill should always be the first choice when applicable. However, when tolerance demands are high and presetting is not an option, CoroDrill 808 will do the job better than any other deep hole drill on the market.

This is a two-dimensional patterned array used for storage and display of various types of information, such as a measurement protocol. Such a protocol includes data on diameter and run out of the drill, making the dot matrix a very safe tool for product identification and traceability. Assortment It is available as a stocked standard item for the STS system with chip breaker geometry 4 and 4 with T-land. Additional configuration options are available for the Ejector system, along with a number of other parameters. A stock standard assortment for stainless steel (Primary products) is also available.
