EXPERIENCE SUPERIOR LIFE AND SPEED WITH M42 COBALT ALLOY

Elevate your drilling performance with the Bosch HBT338 3-3/8 Inch Bi-Metal Hole Saw, engineered for professionals who demand durability and versatility. Crafted from an enhanced M42 alloy containing 8% cobalt, this hole saw is built to withstand high-temperature applications, delivering up to 20% longer life than standard bi-metal saws. Whether you are cutting through tough metal, wood, drywall, or plastic, the reinforced shoulder design provides added strength to handle deep cuts with precision and stability.

Efficiency is at the core of the HBT338 design. It features a unique "Triangle Slot" architecture that significantly improves plug removal and reduces heat buildup during operation. Combined with Bosch's innovative Progressor tooth design—which utilizes alternating tooth sizes—this accessory cuts faster and stays sharper longer across multiple materials. With a generous 1-3/4 inch cutting depth, this tool is the ideal solution for clean, deep boring in complex construction and renovation projects.

Key Features

  • Enhanced M42 Alloy: Contains 8% cobalt to resist high heat and deliver 20% longer service life.
  • Progressor Tooth Design: Alternating tooth sizes ensure faster cutting and superior performance in wood, metal, and plastic.
  • Triangle Slot Design: Specialized "shark tooth" side slots allow for rapid, easy plug removal and better heat dissipation.
  • Deep Cut Capacity: Features a 1-3/4 inch cutting depth to handle thicker materials and multi-layer applications.
  • Reinforced Shoulders: Structural reinforcement adds strength to the saw cup for heavy-duty use.
  • Multi-Material Versatility: Optimized for clean cuts in drywall, metal, plastic, and wood.

Pro-Tip: The "Triangle Slots" on the side of the cup are not just for cooling; they are designed for leverage. If a wood plug gets stuck inside the cup after drilling, insert a flathead screwdriver into the wide part of the triangle slot and twist to easily pop the plug out without damaging the teeth.

Great price. Great fit. Would buy again.
Fit well enough, needed to sand a little for a better fitment. Was not difficult in any way.

Lightweight but so is the original
When the package arrived it was in a very thin lightweight box that was crushed on one side. I thought for sure it was trashed. By chance…all was good. The lights are thin plastic but made very close to the original standard. They fit well on the car but the gasket needs to be tucked in around the edges. That material seems thin. The end result is actually a nice looking inexpensive light. Overall I am happy.
