Notes on using indexable insert drills

Application

Using indexing insert drills (short bore) achieves a multiplicity of productivity and cost savings with HSS spiral bores. The optimum choice of carbide together with the right geometry and feed rate guarantees controlled chip formation.

• Universally applicable WP drill for use on lathes, drills and milling centres. • Can be used as a stationary and rotating tool, both horizontally and vertically • cylindrical shank with face according to ISO 9766 • Bore depths up to 3 x D should not be exceeded • with concave/oblique surfaces the feed rate should be reduced by ca. 30–50 %.

Requirements for good bore results as follows:

• stable clamping • short overhangs, compact drill chuck • correct tool positioning for machine spindle • Use of cooling oil or compressed air at sufficient pressure (chip removal)

Advantages

• Drilling with indexable inserts - economic production of bores or through-holes and blind holes • Very good machining performance with high cutting speeds and feed rates • No running off of the bore axle • direction precise dirlling

• Warning With drill withdrawal a disc drops. Risk of accident with rotating workpieces. Please take precautions!
