The Flexible Hones for Rotors produces the ideal surface finish on disc brake rotors and flywheels.          

1. Lowers Harmonic Vibrations          
Harmonic vibration at the pad-rotor interface is a prime cause of friction induced braking noise. The Flex-Hone for Rotors reduces high pitched "squeal" and "groan" caused by a peaky, rough turned finish.                
2. More Rotors Per Hone            
Lasts much longer than abrasive pads.          
3. Non-Directional Finish            
Spiral grooves on the braking surface are a prime cause of friction induced brake noise.    
         
4. Ideal for New Rotors too!      
Removes the cut, torn and folded metal fragments from the surface. Decreases Ra Values.                

Apwell has engineered and manufactured these Flexible Honing Tools to be competitive with similar products in the market. Apwell's products consistently create an ideal edge break, which is smooth and free of deformed metal. The Flexible Honing Tools are ideal in both automatic and off hand applications.

Flexible Honing Tools have round, abrasive beads fastened to the ends of flexible filaments. This self centering tool will conform to the bore surface providing a consistent, even surface finish over the life of the tool. The Flexible Honing Tool will even provide an "edge break" not possible with conventional honing stones.

Key Features:
1. Sturdy, self-centering stem.
2. Flexible filaments are engineered to provide the correct pressure to create an ideal hone - bore after bore.
3. Rigid abrasive media is firmly attached to the end of the flexible filaments making the tool excellent for tough cross-hole deburring and edge radiusing applications.
4. Fill Material: Silicon Carbide & Aluminum Oxide, Grit choice: #60, #120, #180, #240, #320, #600.
 
Product Size:  
1. Brush diameters ranging from 5mm to 230mm; Round brush(PW556)diameter is 64mm.  
2. Brush length ranging from 50mm to 130mm.  
3. Stem diameters ranging from 1.8mm to 10mm.  
4. Overall length is 200mm.  

Great On:
1. Engine bores
2. Pneumatic and hydraulic bores
3. Valve and pump housings
4. Pipes
5. Connecting rods
6. Cam bores
7. Crank bores
8. Valve bores
9. Hydraulic cylinders
10. Stainless steel tubing

Applications:
1. Honing
2. Creating cross hatched surface pattern for oil retention
3. Cylinder port area deburring
4. Eliminating inside flashing

Instructions:
1. Choose the Flexible Honing Tool for your specific hole size. The actual Flexible Honing Tool will be approx 10% larger than the hole size.
2. Use 10-30 weight oil for honing lubrication, when honing hydraulic brake cylinders, use hydraulic brake fluid as a honing lubricant.
3. Have the Flexible Honing Tool rotating upon entry and removal from the bore.
4. Recommended RPM range for the Flexible Honing Tool is 100 to 1200 RPM, based on the brush diameter. Air Tools are not recommended.
5. Use 60-120 strokes per minute depending on the RPM. Final stroking may be accelerated to develop a 45 degree cross-hatch angle.
6. Honing time should be approximately 20/45 seconds per bore.
7. Do not use solvents for honing or cleaning.
8. Clean cylinders after honing with warm or hot water and detergent using an plain nylon brush, and then lightly oil the bore.
