Product information

Home grinded hand cut drill for stainless steel with a thin core and a shank suitable for NC / CNC machining feed Home Right Diameter: 1.8 mm Length drill Home: short line - see attached photo lengths Home cutting angle: 118 ° (-2 °) Home helix angle: 25 to 30 ° angle Home widths drill head: 25 ° (-2 °) Home Material: HSSE - speed steel Co5 Home Patented developmental row drill: CZ004 Home standard: DIN338
Application: Home Austetická steel, alloy tool and heat-treated high-speed steel in tension of 900 N / mm2 Home High-alloy steel resistant against corrosion, acids and heat

The drill has an extra thin blade at the front of the drill - the narrow core of the drill (see photo). This reduces friction during drilling and can be drilled at higher speeds.
The drill can be easily sanded without reducing the accuracy of the drill hole.

The very thin core , which is constant in the length of the "L1" of the drill bit, significantly reduces the amount of axial force needed for drilling and consequently the development of heat while maintaining the high stiffness of the drill due to the multiple increase of core thickness in the length "L2" continuously towards the bit of the drill.
The constant core thickness at the front of the drill allows its repeated grinding in the length "L1" while maintaining the same geometry of the drill tip.
Small blade width ensures a minimum friction of the bore of the bore hole when it is well maintained.
Special podbrus spikes significantly reduces the friction of the bore of the bore and at the same time creates optimal conditions for the delivery of coolant directly to the cutting point.
Thanks to its geometry, the tip of the drill bit contributes significantly to the drill's hig

"V tomto eshopu jsem nakupoval už před lety, kdy zdaleka nebyly domácí workshopy s mini soustruhy a frézkami tak rozšířené. Nyní jsem zde našel šikovné příslušenství za slušnou cenu a naneštěstí ho hned zaplatil. To že bude zboží k dispozici možná za 3 - 4 týdny jsem nemohl akceptovat, tak jsem objednávku zrušil. Na refundaci jsem si počkal prakticky celou dobu, kterou pravidla umožňují. Nejsem tedy moc spokojený. Přesto obchod doporučuji, protože s výše popsanou nemilou zkušeností zde lze najít spoustu nástrojů, jen radím k opatrnosti při okamitém placení."
