Round #4 Blades 4/32in

The Allstar Performance Round #4 Blades 4/32in (ALL 10793) is a precision tire groover blade engineered for professional drag racing and high-performance automotive applications. These round-profile cutting tools are designed to restore optimal tread depth and grip characteristics on racing slicks, a critical maintenance task for teams operating heated tire grooving systems. Each blade features hardened steel construction and a 4/32-inch groove specification, making it compatible with Allstar's All in One Heated Tire Groover platform.

The 4/32-inch measurement specifies the depth at which the blade cuts, a dimension critical for maintaining consistent tire contact patch and heat characteristics across the friction surface. Round blade geometry distributes cutting pressure evenly, reducing the risk of chattering or uneven groove walls that can compromise tire performance. The steel blade material resists dulling during repeated passes and withstands the thermal cycling inherent to drag strip operations. This set of 12 blades provides multiple replacement units, minimizing downtime during competition season or intensive track testing.

Tire grooving is essential for drag racing teams who need to refresh slick surface texture between heat cycles or across multiple event weekends. The precise depth control offered by numbered blade specifications ensures consistency that impacts launch traction, sustained acceleration, and overall elapsed time reproducibility. Teams managing Allstar heated groover systems rely on standardized blade replacements to maintain the exact cutting geometry their setup was engineered around.

Allstar Performance blades are manufactured to OEM tolerances and packaged in sets designed for frequent replacement cycles typical of professional racing programs. Whether you're prepping for bracket racing, bracket drag racing, or high-stakes competition, having backup groover blades in the pits reduces setup delays and keeps focus on track performance.
