Its stepped design means a single bit covers every size within the range, saving time and reducing tool changes.  The split-point tip allows an easy start without pre-punching, while the CNC ground spiral flute ensures optimised chip removal and minimal vibration for consistent, even drilling. Axial and radial relief grinding delivers the highest cutting smoothness throughout. Built from HSS and coated with AlTiN, the bit offers maximum longevity and requires no coolant. Laser-marked figures on both spiral flutes make diameter identification quick and reliable, and the 3-flat shank locks securely in the chuck for powerful, slip-free torque transmission.  Features and Benefits: \u2022 4mm\u201312mm stepped range \u2014 one bit covers multiple diameters \u2022 Split-point tip for clean starts without pre-punching \u2022 CNC ground spiral flute for optimised chip removal and reduced vibration \u2022 Axial and radial relief grinding for maximum cutting smoothness \u2022 HSS construction with AlTiN coating \u2014 no coolant required \u2022 Laser-marked diameter figures for clear, durable identification \u2022 3-flat shank for secure, high-torque chuck transmission  Specifications: Diameter Range: 4mm\u201312mm","image":"https:\/\/www.tooled-up.com\/artwork\/prodzoom\/2608588064_bo_pro_u_a_1_851172.jpg","images":[{"id":0,"src":"https:\/\/www.tooled-up.com\/artwork\/prodzoom\/2608588064_bo_pro_u_a_1_851172.jpg"},{"id":1,"src":"https:\/\/media.contorion.de\/media\/images\/products\/bosch-stufenbohrer-hss-altin-4-12-mm-6-mm-50-mm-5-stufen-79180946-0-kEgDPt-B-l.jpg"},{"id":2,"src":"https:\/\/asset.conrad.com\/media10\/isa\/160267\/c1\/-\/fr\/000494918PI00\/image?x=100&y=100&ex=100&ey=100&align=center&format=jpg"},{"id":3,"src":"https:\/\/cdn.manomano.com\/fraise-bosch-12-etage-hss-6-a-39-mm-2608597521-L-39725551-166967331_1.jpg"}],"brand":{"id":"68e83d3a-ddab-4d15-b295-314928f925b0","name":"Bosch","image":"https:\/\/static.fnac-static.com\/multimedia\/Images\/16\/16\/8C\/2C\/2919446-1505-1505-1\/tsp20250907094105\/Perceuse-a-percuion-mallette-Bosch-Profeional-GSB-21-2-RCT-060119C700-1300-W-2-vitees.jpg","slug":"bosch","products_count":11056,"visits_count":0,"rating":{"value":4.8,"count":2592,"distribution":[244,67,14,2,3]},"core_categories":[{"id":"632","name":"Hardware","image":"https:\/\/cdn.manomano.com\/pied-de-table-de-bistro-noir-52x52x72-cm-fonte-L-39856046-145412416_1.jpg","products_count":10000,"path":"632","visits_count":0,"href":"\/en-ch\/categories\/632","price_from":2},{"id":"899","name":"Motor Vehicle Parts","image":null,"products_count":10000,"path":"888>5613>899","visits_count":0,"href":"\/en-ch\/categories\/899","price_from":116},{"id":"2977","name":"Motor Vehicle Braking","image":"https:\/\/cdn.autodoc.de\/uploads\/feeds\/atd\/341.png","products_count":10000,"path":"888>5613>899>2977","visits_count":0,"href":"\/en-ch\/categories\/2977","price_from":1065},{"id":"1540","name":"Drill & Screwdriver Bits","image":"https:\/\/asset.re-in.de\/isa\/160267\/c1\/-\/de\/003047517PI00\/003047517PI00.jpg?y=500&x=500&align=center","products_count":10000,"path":"632>3650>3944>1540","visits_count":0,"href":"\/en-ch\/categories\/1540","price_from":45},{"id":"1167","name":"Tools","image":"https:\/\/media.contorion.de\/media\/images\/products\/rothenberger-allgas-2000-handgriff-ohne-brenner-99271259-0-7nd3mpDd-l.jpg","products_count":10000,"path":"632>1167","visits_count":0,"href":"\/en-ch\/categories\/1167","price_from":6}]},"category":{"id":"drill-and-screwdriver-bits","name":"Drill & screwdriver bits","short_name":"Drill & screwdriver bits","image":null,"products_count":12816,"href":"\/en-ch\/categories\/drill-and-screwdriver-bits","has_children":false},"breadcrumbs":[{"id":"diy-garden","name":"DIY & Garden","short_name":"DIY","image":null,"products_count":472519,"href":"\/en-ch\/categories\/diy-garden","has_children":true},{"id":"tools","name":"Tools & Workshop","short_name":"Tools & Workshop","image":null,"products_count":145950,"href":"\/en-ch\/categories\/tools","has_children":true},{"id":"accessories-consumables","name":"Accessories & consumables","short_name":"Accessories & consumables","image":null,"products_count":47537,"href":"\/en-ch\/categories\/accessories-consumables","has_children":true},{"id":"drill-and-screwdriver-bits","name":"Drill & screwdriver bits","short_name":"Drill & screwdriver bits","image":null,"products_count":12816,"href":"\/en-ch\/categories\/drill-and-screwdriver-bits","has_children":false}],"rating":{"value":null,"count":0,"distribution":[]},"currency":"CHF","price":{"symbol":"CHF","currency":"CHF","amount":3195,"offers":2}}}
