DeWALT DT4958-QZ drill bit Twist drill bit 2 pc(s)

APPLICATIONS
Suitable for portable or stationary drilling of high alloy content steels and metals with a tensile strength up to 1100N/mm2 e.g. heat and acid proof steel, cast iron, bronze, welded seams, stainless and chrome nickel steels.

LONG LASTING
5% cobalt content maintains a sharper cutting edge and delivers 4 x longer life (vs HSS-R).

NO-WALK TIP
The ‘no walk’ tip allows for easier penetration of all surfaces (5mm and above). Cleaner, more accurate, burr-free holes due to recessed cutting wings.

SIZE INDICATORS
Away from abrasion and, located outside of grip zone, positioning ensures easy readability (from 5mm diameter and up).

NO-SLIP SHANK
Spin proof 3 sided shaft for optimal grip in drill chuck (diameters 5mm and above only).

STRONG CENTRAL CORE
Increasing in thickness towards the chuck, the central core improves fracture stability, particularly in freehand use (4.8mm diameter and up).

FASTER DRILLING
The optimised tip and flute geometry delivers 4 x the penetration speed (vs HSS-R). It also removes debris faster and reduces heat build up.
