【Perfect Honing】 EWK cylinder honing tool is perfect to deglaze the walls of cylinders in gasoline and diesel engines. Idea for remove burrs and properly roughen the cylinder walls to produce an oil holding cross hatch pattern and provide an adequate seal. 【Smooth Surface Deglazing】Fits 2" to 7" (50.8mm to 177.8mm) diameter brake caliper bores, engine cylinders of automotive, motorcycle and industrial equipment. The 3 pieces adjustable 3" stones cylinder deglazer is perfect to work with 1/4" power drill for effectively creating friction on cylinder bore. 【Highly Flexible】 Adjustable tension screw, controls the spring pressure of stones against cylinder bore to meet different piston diameters. The self-aligning and flexible shaft ensure a smooth movement to get you a nice even hatch pattern bore. 【Durable & Long Lasting & Replaceable】 Made of premium steel, maximize the cylinder honing tool with extra strength and durability. The 220 grit stones are replaceable and will worn out gradually depends on how often you use it. 【Perfect for Mechanics & Small Engine Owners】A practical choice for mechanics, small-engine owners, and hobby builders who need reliable cylinder surface prep without investing in heavy workshop equipment—well suited for entry-level and intermittent honing jobs. This EWK cylinder honing tool is designed for precise cylinder wall deglazing and surface conditioning on both gasoline and diesel engines, helping remove burrs and create a proper oil-retaining crosshatch pattern for improved piston ring sealing. With a working range of 2" to 7" (50.8–177.8 mm), it fits engine cylinders, brake caliper bores, motorcycles, and industrial equipment, making it a versatile solution for multiple applications. The 3-stone adjustable honing head with 3-inch 220-grit stones works seamlessly with a 1/4-inch power drill, delivering consistent friction and efficient surface preparation. An adjustable tension screw allows precise control of stone pressure to match different bore sizes, while the flexible, self-aligning shaft ensures smooth operation and an even hatch pattern. Built from premium steel for durability, the tool features replaceable honing stones for extended service life. Ideal for mechanics, small engine owners, and DIY builders, this honing tool provides reliable cylinder preparation without the need for bulky workshop equipment—perfect for entry-level rebuilds and routine maintenance.
