## Summary description

AWTools AW18721BL is a car crank (piston/component) designed for automotive repair and engine maintenance. The part is specified by model AW18721BL and has a weight of 130 g. It serves as a replacement component in compatible engine assemblies, suitable for mechanics and DIY vehicle servicing where a lightweight crank/piston component is required.

## Long description

AWTools AW18721BL is a compact car crank-style piston/component accessory designed for cleaning and light machining inside cylindrical engine and hydraulic parts. Weighing 130 g, the tool features three arms with grit stone-equipped jaws and a flexible shaft that provides self-centering action and access in confined spaces. The jaws are made of hardened steel for durability and the abrasive stones press against bores with adjustable pressure via a spring and knurled nut. The AWTools AW18721BL is intended as a replacement or service tool compatible with standard electric drills and three-jaw chucks for maintenance of brake cylinders, clutches, small engine bores and other cylindrical surfaces.
Advantages
The design combines hardened-steel jaws and replaceable grit stones to deliver wear resistance and consistent abrasive action. Its flexible shaft and self-centering three-arm layout make it easier to reach and align within tight or offset bores. Adjustable stone pressure via a knurled nut and spring mechanism allows controlled material removal and safer contact with cylinder walls. The compact 130 g form factor keeps rotational inertia low, allowing stable operation with standard electric drills and common three-jaw chucks.
Suitable for
 Cleaning and light resurfacing of car brake cylinders and clutch housings
 Deburring and honing motorcycle and small engine cylinders
 Maintenance of lawnmower and outboard engine bores
 Degreasing and light abrasion of hydraulic cylinders and machine engine bores
Key specifications
 Weight: 130 g
 Three-arm configuration with self-centering action
 Jaws: hardened steel for strength and wear resistance
 Abrasive elements: grit stones mounted on jaw ends
 Adjustable stone pressure: spring with knurled nut
 Flexible shaft for maneuverability in tight spaces
 Compatible with standard electric drills and three-jaw chucks
How to use
Mount the AWTools AW18721BL into a compatible three-jaw chuck of a standard electric drill, ensuring the flexible shaft and jaws are securely seated. Insert the tool into the bore to be cleaned, engage the drill at low to moderate speed and allow the self-centering arms to align. Adjust the pressure of the grit stones against the cylinder wall by turning the knurled nut to compress or release the spring, then work the tool along the surface in steady passes until the desired cleaning or light honing is achieved. Periodically stop and inspect the surface and stones, replacing abrasive elements if worn.
Usage recommendations
Use eye and hand protection when operating with a drill. Start at low drill speed to verify alignment and avoid excessive material removal; increase speed only as necessary for effective abrasion. Clean and degrease the bore after use and replace grit stones when significantly worn. Avoid high-speed applications on thin-walled components to prevent distortion.
