Even with aition of 5 % Co in the cutting material these rill bits can be use for working with work pieces with a tensile strength of over 800N/m².

$It has the best possible true running accuracy an therefore prouces exact roun holes. It has a long tool life an ue to its conically strengthene high resistance against fracture.$ $Especially when rilling with iameters below 6 mm the anti-torsion capability is very high while the anger of fracture is low.$

3 Metal rill bits Stronger than steel Nothing stops the metal rill bits because we offer a rill bit for every application. 135 HSS-E twist rill bit The HSS-E rill bit is a cobalt alloye high performance rill bit. Even with aition of 5 % Co in the cutting material these rill bits can be use for working with work pieces with a tensile strength of over 800N/m². 118 HSS twist rill bit Split Point This rill bit allows precise pilot rilling even on iagonal surfaces. The avance force ecreases by 50 %. It has the best possible true running accuracy an therefore prouces exact roun holes. It has a long tool life an ue to its conically strengthene high resistance against fracture. 118 HSS twist rill bit ue to its robust thickness of core an a istinctive harness this rill bit has a long tool life. Especially when rilling with iameters below 6 mm the anti-torsion capability is very high while the anger of fracture is low. It is very suitable for working with alloye an unalloye steel, non ferrous metals, cast iron an har plastics. 135 HSS pilot rill bit cylinrical. The HSS pilot rill bit allows exact pilot rilling without slipping ue to its self centering tip. This extra short rill bit is particularly suitable for use with han-hel machines. 120 HSS twist rill bit with carbie bit The rill bit has been groun with iamon wheels to the highest accuracy. The 2-bevel sharpening buils a centering tip which is locate exactly in the rilling axis whereby the rill bit centers itself.when working with CNC-machines it offers best performance. 70

4 Metal rill bits Cylinrical shaft Tools with roun shaft are the top selling rilling tools. The roun shaft is Hexagonal shaft (10.0 mm) The hexagonal shank offers a better transmission of rotation especially when working with big iameters an long rill bits. Morse taper The morse taper (MK) is the stanarise shape of a tool conus for clamping tools, e.g. rill bits with big iameters, reamers an chuck in the tool intake of a machine tool. Most tool intakes of rilling machines an turning lathes have the sizes MK2 up to MK6. KEILBIT (E 6.3 mm) be use for rilling. The KEILBIT has specially been invente for the fast an irect application in these machines. No change of machines is necessary anymore. For the various materials we offer ifferent alternatives of the KEILBIT. KEILBIT (C 6.3 mm) This is a ifferent kin of shaft of the KEILBIT with short hexagonal shank an short rill bit. 71

16 HSS IN 338 stanar Prouct information The KEIL HSS twist rill bits IN 338 stanar have a high elasticity ue to heat forming. The rill bit has a particularly robust core thickness an istinct harness resulting in a long tool life. Col eposition is reuce by the special surface treatment. The achieve torsional strength leas to little anger of breakage, in particular when rilling holes of less than 6 mm iameter. This twist rill is the conventional tool for professional use in metal. The rills are excellent for machining alloye an unalloye steel with a tensil strength up to 800 N/mm², non-iron metal, cast iron an har plastics.

Our spee table gives recommenations on cutting spees an fee rates. epening on the actual working conitions it may, however, be necessary to etermine iniviual cutting values by means of tests. The cutting values shoul be reuce by 20 to 40 per cent for horizontal holes an for rilling epths which are o not overheat rill bit High-alloy an heat-resistant materials can only be properly cut with the use of coolants, with special cutting zone. or materials with a low tenency to ahesion. Materials forming short chips, such as brass an cast iron, but also plastics, shoul be machine without coolant. the coolant can penetrate properly into the hole. In particular, this must be observe for holes which are three times eeper than the iameter (3 x ø).this also Woo rill Bits Metal rill Bits Percussion rill Bits Hammer rill Bits Correct re-grining The correct tip grin of a rill bit is the basic conition for economic rilling. Thus timely re-grining an, in particular, grining to the correct shape of the cutting eges is essential for uninterrupte prouction. KEIL recommens re-grining with one of the tip grining machines for twist rill bits available in the market, as only these machines ensure the setup for optimum re-grining of the main cutters, cutter corners, lan an chisel eges. Manual regrining is not recommene as this is too imprecise, leas to early nonrecoverable wear of the rill bits an oes not allow accurate holes to be rille.
