Impact Spiral Bits.  Tips are CNC Machined.  Made for Impact Tools.

ImpactechTM Spirals Absorb Impact Bits. These bits are designed for use with Impact Tools and the tips are CNC machined. 
Sold individually, though there are (5) per pack, we offer these with a #2 Phillips Drive or a #2 Square Drive. 
Other sizes are available upon request.

Importance of Impactech TM Spirals (Torsion Zone) in Absorbing Impact

The patented spiral torsion zone in Impactech TM bits is a key engineering feature designed to absorb and dissipate impact forces generated when driving fasteners with power impact tools.  This spiral-shaped torsion zone is machined into the bit’s shank, allowing it to flex slightly during rotation.

Why it’s important:

• Extends Bit Life – By absorbing shock and torsional stress, the spiral torsion zone reduces the risk of tip breakage and shank fractures. This design has been tested to outperform leading brands in lifecycle and tip failure testing, with Impactech TM bits lasting on average twice as long as competitors.
• Reduces Stress on Fastener Tips – The torsion zone helps manage the twisting forces applied to the bit tip, which in turn improves the fit and reduces stripping of screws or bolts.
• Improves Durability in High-Torque Tasks – Made from S2 modified shock-resistant steel and precision CNC-machined tips, the spiral torsion zone works with the bit’s overall construction to handle high torque and repetitive fastening without premature wear.
• Enhances Performance in Power Tools – The design is specifically engineered for professional power impact tool use, where high-speed impacts and repeated fastening cycles are common. The spiral torsion zone ensures consistent performance and reliability over extended use.

In short, the Impactech TM spiral torsion zone is a critical durability feature that protects the bit from impact damage, prolongs its service life, and maintains precision in fastening applications. This makes Impactech TM bits a preferred choice for professionals who need long-lasting, high-performance driver bits.
