SDS-plus drill bit set
HERMAN QDC-24 Triton
5 drill bits in set

Massive carbide head of triple-bit design mounted as one unit in the drill body:
stable design with very high resistance to steel reinforcement

Centring tip in the centre of the head:
allows precise drilling of holes

Carbide insert bits at 150˚:
optimised angle to allow easier drilling of the reinforcement and minimise lateral damage to the drill bit

Drill body made of high-strength Cr-Ni-Mo steel, with blast-treated surface:
high resistance to lateral stresses, breakage of the drill bit during erection is very unlikely

Asymmetric double helix with initial run-up directly at the drill head:
It reduces drilling friction and contributes to increased drilling speed by immediately diverting the drilled material away from the drill head

PGM mark on the drill shank:
guarantee of compliance of the drill diameter tolerance with the standard for drilling precision holes for dowels and anchors

Recommendation:
When using drill bits with a working length of 400 mm or more, it is necessary to pre-drill a hole of the same diameter with a depth of at least 150 mm, with a working length of 800 mm or more, at least 350 mm

Recommendation:
Lubricate the drill shank with grease. This will prevent premature wear and prolong the life of the quick-release system in your drill hammer
