Saber® SF-5 Tree Radius Nose Tungsten Carbide Burr | 1/2" Head | 1/4" Shank | 8020-SF5

Express Cut Double-Cut Carbide Burr for Rapid Stock Removal, Deburring, Shaping and Weld Preparation

Supply Solutions Group supplies the Saber® SF-5 Tree Radius Nose Burr – 1/2" (Part Number 8020-SF5) to organisations operating across fabrication, engineering, manufacturing, mining, automotive, maintenance, welding and industrial workplaces throughout Australia.

The Saber SF-5 Tree Radius Nose Burr is a professional tungsten carbide rotary burr designed for rapid stock removal, shaping, deburring and material preparation using compatible high-speed rotary tools.

Featuring an SF-5 tree radius nose profile, the burr combines a tapered tree-shaped cutting head with a rounded nose, making it particularly useful for working on curved profiles, radiused surfaces, welds and difficult-to-access contours.

The burr has a 1/2-inch head diameter with a 1-inch flute length, providing a substantial cutting surface for medium to heavy material-removal applications.

A standard 1/4-inch shank allows the burr to be used with compatible die grinders and other suitable rotary tools equipped with the correct collet.

The overall tool length is approximately 2-3/4 inches.

Saber manufactures this burr from tungsten carbide, providing the hardness and wear resistance required for demanding metalworking and industrial applications.

The cutting head uses Saber's Express Cut, also referred to as a Double Cut, tooth configuration.

Double-cut carbide burrs incorporate intersecting cutting flutes that create smaller chips compared with conventional single-cut burrs.

Bordo states that this design supports rapid stock removal and improved operator control, while allowing lower operating speeds than standard-cut burrs in appropriate applications.

The smaller chip size can also make the tool easier to control during grinding, shaping and deburring tasks.

The Saber SF-5 is suitable for use on a broad range of materials including:

• Carbon steel

• Cast iron

• High-strength steel

• Stainless steel

• Steel castings

• Steel welds

• Titanium alloy

• Fibreglass composite

This versatility makes the burr suitable for fabrication workshops, engineering departments, mining maintenance teams and other environments where one rotary tool may need to work across multiple materials.

Typical tasks include removing excess weld material, smoothing rough edges, enlarging or shaping openings, preparing welds, deburring machined components and blending contours.

The rounded nose provides additional control when shaping curved recesses and internal profiles compared with flat-ended burr geometries.

Correct operating speed and technique are important for carbide burr performance.

Bordo advises using constant movement and light pressure during operation rather than forcing the burr into the workpiece.

Harder materials generally require slower running speeds, while smaller burrs generally require higher speeds.

Operating below the appropriate speed can contribute to tooth chipping, while excessive speed can cause premature tooth wear.

Why Choose Saber® SF-5 Tree Radius Nose Burr?

The Saber SF-5 combines tungsten carbide construction, a versatile tree-radius profile and double-cut geometry for demanding material-removal applications.

Carbide burrs are commonly selected where operators need greater material-removal capability and service life than conventional files or abrasive tools can provide.

The tree radius nose shape is particularly useful for working around curves and internal contours.

Its tapered profile allows the operator to work into progressively narrower areas, while the rounded nose helps blend curved surfaces without introducing a sharp flat-ended profile.

This makes the SF-5 useful for applications including:

• Weld contouring

• Internal radius work

• Component shaping

• Casting clean-up

• Edge blending

• Deburring

• Surface preparation

Express Cut / Double Cut Design

Saber describes the SF-5 as an Express Cut tungsten carbide burr.

Express Cut is also referred to as Double Cut.

The intersecting flute pattern creates smaller chips and provides greater operator control than a conventional standard-cut burr.

Bordo identifies the main benefits as:

• Rapid stock removal

• Improved operator control

• Reduced chip size

• Ability to use lower speeds compared with standard-cut burrs in appropriate applications

This makes double-cut burrs particularly useful for general-purpose industrial material removal.

1/2" Tree Radius Nose Profile

The SF-5 head has a diameter of:

1/2 inch

The cutting flute length is:

1 inch

This provides a useful cutting area for medium and heavier-duty shaping and deburring tasks.

The radius nose helps the operator work smoothly across curved profiles and recesses.

1/4" Shank

The burr uses a:

1/4-inch shank

This is a common professional carbide-burr shank size and is compatible with many industrial die grinders and rotary tools using a suitable 1/4" collet.

Always confirm the tool and collet are in good condition before fitting the burr.

Suitable Materials

Bordo specifically identifies the Saber Express Cut range for use on:

• Carbon steel

• Cast iron

• High-strength steel

• Stainless steel

• Steel castings

• Steel welds

• Titanium alloy

• Fibreglass composite

Material hardness affects the appropriate operating speed and feed technique.

Operating Technique

Bordo recommends:

• Maintain constant movement

• Apply light pressure

• Avoid forcing the burr into the material

• Use slower speeds on harder materials

• Use faster speeds for smaller burrs

• Use appropriate speeds for the specific tool and substrate

Allowing the burr to remain stationary in one area may generate excessive heat and reduce tool life.

Important Speed Considerations

Correct rotational speed is essential when using tungsten carbide burrs.

Bordo advises that:

• Running too slowly may contribute to chipping

• Running too fast may cause premature tooth wear

• Excessive heat may soften the braze securing the carbide head

• A softened braze can potentially cause the head to detach from the shank

Always use the manufacturer's recommended speed chart for the burr diameter and workpiece material.

Do Not Over-Engage the Burr

Bordo specifically advises operators not to sink the burr into the workpiece for more than one-third of its periphery.

Excessive engagement can place unnecessary load on the carbide head and increase the risk of:

• Chipping

• Vibration

• Poor finish

• Reduced tool life

• Tool damage

Use controlled passes instead of forcing the entire burr profile deeply into the material.

Tool and Collet Condition

Worn tools or collets can create excessive runout and vibration.

Bordo notes that worn tools and collets can contribute to carbide chipping.

Before operation:

• Inspect the burr

• Inspect the shank

• Inspect the collet

• Ensure the burr is securely clamped

• Check the grinder for excessive vibration

• Replace worn components

Important Safety Information

Carbide burrs operate at high rotational speeds and can generate sharp chips and airborne debris.

Users should:

• Wear suitable eye protection

• Use face protection where required

• Wear appropriate hearing protection

• Wear gloves where permitted by the tool and workplace procedure

• Use suitable respiratory protection when dust hazards exist

• Secure the workpiece before cutting

• Use only compatible rotary tools and collets

• Do not exceed recommended operating speeds

• Apply light, controlled pressure

• Maintain constant movement

• Keep loose clothing and hair away from rotating equipment

• Allow the tool to stop completely before putting it down

• Inspect the burr before each use

• Never use a chipped or damaged carbide burr

Fibreglass and composite machining can create hazardous airborne dust, so appropriate dust-control and respiratory-protection measures should be used.
