Why Choose the Klingspor KM 613?

The KM 613 is specifically designed for applications where a conventional grinding disc or larger abrasive wheel may not be practical.

Its compact:

40mm x 20mm

working dimensions and:

6mm Shaft

allow the wheel to access smaller and more complex workpiece areas.

Klingspor describes the KM 613 as a specialist for difficult-to-reach areas, with a soft and flexible flap structure that adapts to complex surface shapes. (WeldQuip)

Aluminium Oxide Abrasive Grain

The KM 613 12944 uses:

Aluminium Oxide

abrasive grain with a resin bond. (Gasweld)

Aluminium oxide is a versatile abrasive suited to a broad range of workshop materials and general-purpose finishing operations.

This contributes to the KM 613's suitability across:

• Stainless steel

• Metal

• Wood

• Plastic

P80 Grit

This model uses:

P80 Grit

P80 provides a practical intermediate abrasive grade that balances material removal with surface refinement.

It is particularly useful for:

• Removing moderate surface marks

• Blending

• Deburring

• Refining previously ground areas

• Preparing surfaces for subsequent finishing

For heavier stock removal, a coarser grade may be preferred, while finer grades can be used where a smoother final surface is required.

40mm Diameter

The working wheel diameter is:

40mm

The compact diameter makes the KM 613 useful for components and areas that cannot easily be processed using a conventional full-size flap disc.

20mm Working Width

The wheel provides a:

20mm Working Width

offering a useful abrasive contact area while retaining the compact dimensions needed for detailed finishing work.

6mm Shaft

The KM 613 is supplied with an integrated:

6mm Shaft

for mounting in compatible power tools.

Klingspor describes the KM 613 as suitable for appropriate straight grinders and drilling machines with speed control. (WeldQuip)

Always confirm tool compatibility and operating speed before use.

Flexible Flap Construction

A defining feature of the KM 613 is its flexible arrangement of abrasive flaps.

As the wheel rotates, the individual flaps can conform more readily to the workpiece than a rigid abrasive.

This is particularly advantageous for:

• Contours

• Irregular surfaces

• Internal areas

• Curved components

• Detailed metalwork

• Difficult-to-access locations

Klingspor notes that the flexible movement of the flaps also provides additional ventilation during operation. (Gasweld)

Cooler Grinding

The movement of the individual abrasive flaps supports airflow through the wheel during operation.

This ventilation helps provide cooler grinding and can help reduce unwanted heat effects on the workpiece.

Klingspor specifically highlights this characteristic when describing the KM 613's performance on stainless steel. (Gasweld)

Constant Removal Rate

The KM 613 is designed to provide a:

Constant Removal Rate

during use. (Gasweld)

As the abrasive flaps wear, fresh abrasive material is progressively exposed, helping maintain effective cutting and finishing performance.

Stainless Steel Applications

Klingspor specifically lists:

Stainless Steel

as an application for the KM 613. (Gasweld)

Typical stainless-steel applications can include:

• Surface finishing

• Weld-area refinement

• Blending

• Edge finishing

• Processing complex fabricated components

Where contamination control is important, use abrasives and tools according to appropriate stainless-steel fabrication procedures.

General Metal Applications

The KM 613 is also suitable for:

Metal

making it useful for a broad range of workshop and fabrication applications. (Gasweld)

Its compact dimensions are especially advantageous when working around intricate components.

Wood Applications

Klingspor also specifies the KM 613 for:

Wood. (Gasweld)

The flexible flap construction can be useful when sanding shaped or contoured timber components where a rigid sanding surface may be less effective.

Plastic Applications

The KM 613 is additionally suitable for:

Plastic. (Gasweld)

Appropriate speed and pressure should be selected for the specific plastic material to manage heat generation and achieve the required finish.

Difficult-to-Reach Areas

One of the main advantages of a spindle flap wheel is accessibility.

The KM 613's small diameter and shaft-mounted design make it particularly useful for:

• Internal corners

• Recesses

• Contoured components

• Small fabricated parts

• Tight spaces

• Irregular surfaces

Klingspor specifically describes the KM 613 as designed for processing hard-to-reach areas and complex surface shapes. (WeldQuip)

Straight Grinder & Drill Compatibility

The KM 613 can be used with suitable:

• Straight grinders

• Drilling machines with speed control

provided the tool accepts the 6mm shaft and can be operated within the abrasive's speed limitations. (WeldQuip)

Always confirm the manufacturer's requirements for both the abrasive and power tool.

Maximum 19,000 RPM

For catalogue number 12944, Klingspor specifies:

Maximum Speed: 19,000 RPM

and:

Maximum Peripheral Speed: 40m/s. (Klingspor)

Never operate the flap wheel above the maximum permissible speed.

Box of 10

This listing contains:

10 x Klingspor KM 613 P80 Spindle Flap Wheels – 12944.

Unlike some repacked abrasive listings, the box quantity here matches Klingspor's standard manufacturer packing unit of:

10 Wheels. (Klingspor)

This makes the pack suitable for workshops, fabrication facilities and maintenance teams with regular abrasive requirements.

Available KM 613 Grits in This Size

Klingspor's current technical data lists several grit grades for the 40 x 20 x 6mm KM 613, including:

• P40 – 12942

• P60 – 12943

• P80 – 12944

• P120 – 12946

• P240 – 12949. (Klingspor)

This allows users to select different abrasive grades depending on the required balance between stock removal and surface finish.

Safety Considerations

Powered abrasive operations can generate:

• Abrasive particles

• Workpiece debris

• Dust

• Noise

• Heat

Appropriate workplace controls and PPE should be selected for the material, tool and task.

This may include:

• Safety glasses or goggles

• Face protection where required

• Hearing protection

• Appropriate gloves

• Protective clothing

• Respiratory protection where required

Always follow Klingspor's abrasive safety requirements and the power-tool manufacturer's instructions.

Storage & Handling

For best abrasive condition:

• Store in a clean, dry location

• Protect from excessive moisture

• Avoid excessive heat

• Prevent damage to the abrasive flaps

• Protect the spindle from bending

• Inspect the wheel before installation

• Do not use damaged abrasive products

• Keep products appropriately packaged until required
