2 The botek company Manufacturing deep and precise holes is a technical challenge when processing metal. Accordingly specialising in deep hole drilling technology was the founding idea in 1974 of botek Präzisionsbohrtechnik GmbH in Riederich. botek grew to be an international supplier of deep hole drilling tools. Over 500 employees in the main company develop and manufacture single and two fluted drills, deep hole drilling tools BTA and Ejector systems as well as special tools. A complete product program, regarding all deep hole drilling aspects and a team of highly qualified and dedicated cutting specialists make botek a competent partner for the automobile industry and their suppliers, shipbuilding industry, hydraulic industry and aviation industry as well as motor, gear and machine building companies. Our General Terms and Conditions which we assume are known to be applied. The values specified in this catalogue (e. g. for feedrate, coolant, pressure and coolant quantity, etc.) are guide values only and can vary depending on your application. We reserve the right to make changes of any nature in the interests of technical progress. Such changes cannot, in principle, be accepted as a complaint. Subject to change without prior notice. Errors excepted. Please see our application notes, botek Präzisionsbohrtechnik GmbH 2

3 t t t Advantages / Informations Type 11 / Type 61 botek advantages 1. New, high-performance solid drill heads with a modern, user-friendly design. 2. Very high operational efficiency combined with optimum cutting performance. 3. Ideally suited to deep hole drilling machines. 4. No regrinding needed. 5. Various indexable insert chip breakers are available according to material to be processed. Coated indexable inserts and guide pads are also available. 6. Easy exchange of indexable inserts and guide pads. No need to adjust setting within ± 0.01 mm diameter. 7. When using matching interchangeable parts, the drill head diameter may, however, be adjusted within a range of 1.0 mm. 8. Easy assembly onto the drill tube with an open-end wrench. 9. Drilling tolerance up to IT7 is possible under favourable conditions. Type 11 Solid drill head system BTA 1-start connection thread Type 61 Solid drill head system BTA 4-start connection thread Information about botek solid drill heads Type 11/Type 61 - The chip breaker has a decisive part to play with the chip formation. - To obtain trouble-free chip flow along with optimum tool life, it is essential to aim for the most ideal chip formation possible. - The chips should be broken just short enough to ensure that there is no chip congestion in the flute or the drill. - Excessively short, crushed chips place strain on the cutting edges and lead to premature wear and will destroy the cutting edge. - For processing commonly used materials, indexable inserts are available from stock with chip breakers SP 1 or SP 2. Chip breaker SP 1 Chip breaker SP 2 Chip breaker SP 3 - Unalloyed steels C>0.2 - Unalloyed steels C<0.2 - According to b, t, r, or drawing - Alloyed steels - Long chip-forming special steels - Toughened steels - Stainless and acid-proof steels - Case hardened steels - Tool steels - Stainless and acid-proof steels Drilling range (mm) Indexable insert b Chip breaker SP 1 Chip breaker SP 2 b t r b t r b b b b b b r r r b b
