JG.BROCA HSS - R 29PC

- Set of 25 spiral drill bits DIN 338 type VA Ø 1,0 mm up to 13,0 mm x 0,5 mm

- High-performance rolled, steam-treated twist drill made from heavy- duty high speed steel.
- The manufacturing procedure (no structural disruption) solidifies the material making it more elasticated.
- This makes it more resistant to fracture and suitable for robust drilling units. (e.g. hand-held drilling machines)

- High performance twist drill for all-purpose use in drilling machines and cordless drills. (Materials up to 5,0 mm thickness)
- The 3-surface-shank provides an excellent fixing within the drill chuck with little effort. In addition, the shank ensures an ideal power transmission. No spinning of the drill!
- The 135º high performance cutting edge ensures a very high aligned preciseness, particularly when hand-operated with a cordless drilling machine. The edge prevents sliding off corrugated surfaces whilst spot-drilling.
- Increased wear resistance of the rechargeable battery due to reduction of cutting forces.
- The black bevel increases the wear resistance and prevents cold welding and build-up edges.
- The 40º helix angle enables a perfect and fast chip removal and provides a high cutting speed along with increased stability and accuracy. HSSE-Co 5:
- Heavy-duty high speed steel with 5 % cobalt content.

- Set of 25 spiral drill bits DIN 338 type VA Ø 1,0 mm up to 13,0 mm x 0,5 mm

Powerful special drill that should ideally be used for titanium base alloys as well as stainless, acid-resistant and heat-resistantaustenitic steels. It is also suitable for high strength steels with low ductility. Under certain conditions, these drills can be used for special alloys such as hastelloy, inconel and nimonic etc. HSSE-Co 8: Heavy-duty high speed steel with 8 % cobalt content.Extremely high ductility and outstanding heat resistance, for drilling holes in high strength materials, austenitic steel, for hot working etc. with a strength of up to 1100 N/mm².The titanium aluminium nitride coating offers high heat and oxidation resistance. Suitable for drilling hard materials without lubrication. Max. application temperature 700 ºC

- Set of 50 spiral drill bits DIN 338 type VA Ø 1,0 mm up to 5,9 mm x 0,1 mm
