Design and Construction — a VPOINT tungsten carbide burr bit in the standard SA–SM head-code system, sized for steel / stainless welds and similar work. YG8 carbide at HRA 89–91; die-grinder reference speeds are in the performance table below, with the flute-style guidance in the FAQ. ISO 9001 production, batch-verified, custom sizes from drawings.

Design and Construction

SF-5: tree shape with radius end, 6 mm head class, on a 1/4 inch shank – the professional standard for radius blending. Ground to the published dimension table and tube-packed with the code printed.

How It Works

The radius-end tree rolls along transitions without stepping; at about 40,000 RPM it blends radii and dresses welds in controlled passes.

Applications

Radius blending, weld dressing, mould and die finishing, fabrication rework.

Field Cases

• Mould shop: SF-5 blends EDM transitions where a cylinder stepped.
• Fabricator: crown blending on 6 mm plate welds – the standard code every hand knows.
• Maintenance: tube codes ended shape mix-ups between shifts.

Performance Data

Suitable Materials

Steel, cast iron, stainless steel and non-ferrous metals.

Material Comparison: SF-5 vs a Generic Tree Burr

What professional grade means against an unbranded tree head:

Delivery Scope

Burr in printed tube; other SF sizes stocked for the ladder.

Why Choose VPOINT

A single proven code, dimension-verified – the professional default.

Precision & Quality Control

Radius profile template-checked per batch.

Frequently Asked Questions

Which head code do I need?

＋The SA–SM code defines the contour: SA cylinder, SC ball-nose end, SD ball, SF tree-pointed, SH tree-radius, SL tree-tapered, SM cone. Match the contour to the cavity or corner you are shaping.

Can I use one burr across different metals?

＋Yes with the right flute style — double-cut for steel and iron, Aluma-cut for aluminium and soft non-ferrous. Swapping styles between jobs keeps edges clean.

Are custom shanks or head sizes available?

＋Yes — non-standard head diameters, shank sizes and logo marking are produced to order from drawings.
