3 in 1: drilling, thread cutting and countersinking/deburring in one work step
No tool change required, saving time and costs
SMART STEP technology
- Work up to 100 % faster than with conventional combination screw taps
- Optimal centring even when working on curved surfaces
- High-precision, circular drilling as ideal preparation for the quality of subsequent thread cutting
- Effortless drilling
The premium combination screw tap is suitable for thicker workpieces in addition to machining sheet metals
Enables double the depth of drilling, thread cutting and countersinking/deburring compared to conventional combination screw taps (2xD instead of 1xD)
The premium combination screw tap is suitable for almost all materials
SMART STEP technology and HSCo cutting material
Significantly longer service life compared to conventional combination screw taps
SMART STEP technology and HSCo cutting material
True-to-the-gauge through hole thread according to ISO 2 (6H)
Newly developed shank generation with a combination of 3-flat and straight shank with square drive
The 3-flat shank prevents spinning in the drill chuck, ensures optimal power transmission and protects the drill chuck from damage
Product packaging made of 100 % PCR (recycled plastic from household waste), 100 % recyclable and Cradle to Cradle Certified® Bronze
Available exclusively from Würth
- Only suitable for through hole threads
- Countersinks in accordance with DIN 74-1 for countersunk head screws (in accordance with DIN 7991) are not possible.
- For use in cordless drill drivers as well as on hand-held, pillar and upright drills.
- Sufficient coolant and lubricant must be added.
Datasheets(X)
- Suitable for through holes in non-ferrous metals, such as aluminium and brass, and plastics with a material thickness of up to 2xD, for both hand-held and stationary use.
- Suitable for machining steel materials up to 1,000 N/mm² and cast metal with a material thickness of up to 2xD in stationary use; for material thicknesses of up to 1.5xD in hand-held use.
- Suitable for machining stainless steels and titanium with a material thickness of up to 1xD in stationary use.
- After the drilling process, it is essential to significantly reduce the rotation speed for thread cutting and countersinking/deburring.
- Sufficient coolant and lubricant must be used.
- Be sure to work in a straight line. Avoid tilting at all costs: Risk of tool breakage!
- Before reversing the combination screw tap, make sure to remove all threads of the tool from the drill hole. Failure to do so may cause cutting edges to chip or the tool to break.
