Flex-Hone® tool for metal surface treatment

Efficient honing and deburring for the highest surface quality

The Flex-Hone® is a highly flexible and robust tool specially designed for honing and deburring cylinders and bores. With its unique combination of flexible nylon filaments and firmly anchored abrasive beads, it offers excellent surface finishing in just one operation. Ideal for technical users in metalworking, Flex-Hone® offers reliability and versatility while reducing the amount of work required.

Main features and benefits of Flex-Hone®

Self-centring and self-aligning: Flex-Hone® automatically adjusts to the drill hole without the need for complex clamping devices. It adjusts itself during use and compensates for wear.

Wide range of applications:

High versatility: Suitable for hand drills, CNC machines and all types of machining centers. No complex set-up required
Combined honing and deburring: Flex-Hone® enables both surface refinement and burr removal in a single work step. This saves you valuable time and increases efficiency.

Applications and possible uses

Flex-Hone® is ideal for a wide range of industrial applications and is particularly suitable for

Hydraulic and pneumatic cylinders: Surface refinement and protection of seals through precise honing
Preparation for coatings: Ideal for pre- and post-processing of electroplating and other coating processes
Cross-hole deburring: Removes burrs on edges and cross-holes for improved surface structure and functionality
Machining of cast and welded metal parts: Edge rounding and avoidance of sharp burrs
Repair of cylinders: Smoothing of worn edges and reconditioning of smooth-running cylinders for piston ring replacement
Cleaning and polishing: Flex-Hone® removes flash rust and ensures an even surface

Technical specifications and selection options

Flex-Hone® tools are available in a wide range of diameters, abrasive types and grain sizes to ensure optimal adaptation to different materials and processing requirements:

Diameter range:

Standard sizes from 4 mm to 914 mm for almost any application, from small precision work to machining large cylinders

Abrasive types:

Silicon carbide (SC): For standard materials such as mild steel, stainless steel and cast iron. Excellent for aggressive material processing and fast stock removal.

Aluminum oxide (AO):

Zirconium aluminum oxide (Z-grain): Especially for steels with a higher carbon content or for applications that require a longer service life.
Diamond: For particularly hard materials such as hardened tool steel, carbide and ceramics.

Grit options:

Flex-Hone® offers 14 grit options that can be selected depending on the desired surface finish:

Coarse grit (20 - 80): Ideal for intensive material removal and robust deburring
Medium (120 - 240): For standard surface finishes with a fine structure
Fine (320 - 600): Suitable for a smooth and precise finish
Ultra-fine (800): For high-precision work and extremely smooth surfaces

Recommended application parameters

Speed: The optimum speed depends on the tool diameter and ranges from 60 to 1,200 rpm. Larger tools work at lower speeds, while finer grit sizes require higher speeds
Lubricants: The use of Flex-Hone® oil or a light motor oil is recommended for a long service life and an even surface. Lubricants reduce heat development and prevent sanding particles from sticking together.

Processing time:

Perfect finish and plateau structure

Flex-Hone® offers a high-quality plateau finish that ensures an even surface to which lubricants adhere optimally. This surface is particularly suitable for applications where durable sealing performance is required, such as hydraulic cylinders and motors.
