The DiZiK 3-Flute Roughing Spiral Bit is a premium-grade cutting tool engineered for heavy-duty roughing applications. Manufactured from ultra-fine solid carbide and finished with a gold TiN (Titanium Nitride) coating, this bit offers a perfect balance of strength, heat resistance, and wear protection.
Its wave-form (serrated) cutting edge excels in fast material removal, breaking chips into finer pieces for cooler, cleaner cutting. The triple-flute design enhances chip evacuation and improves cutting stability at high speeds.
Whether you're machining hardwood, MDF, plywood, or composite panels, this tool delivers aggressive cuts with consistent quality, making it a go-to choice for professionals in cabinet making, furniture production, and CNC routing.
Solid Carbide Body: Maximum rigidity, edge retention, and longevity
Triple-Flute Design: Boosts chip clearance and reduces vibration
Wavy (Serrated) Cutting Edge: Fast chip removal and cooler cutting
TiN Gold Coating: Reduces friction, extends tool life, and resists heat
Upcut Spiral Geometry: Improves cut accuracy and chip removal
Perfect for CNC Machining: Compatible with nesting, trimming, and shaping operations

Install the bit securely into the correct collet size to avoid vibration.
Adjust RPM and feed rate based on material — avoid excessive speed to prevent overheating.
Use this bit for rough passes, followed by a finishing bit for surface quality.
Clean regularly with resin remover or non-corrosive cleaner to maintain coating and sharpness.
Store in a dry place, ideally in a tool rack or protective case.
Q1: What is the purpose of the wavy cutting edge?
The serrated, wave-form edge breaks chips during the cut, reducing friction and heat while improving feed speed during roughing operations.
Q2: What’s the advantage of the gold TiN coating?
TiN (Titanium Nitride) coating reduces wear, increases surface hardness, and allows longer running time without tool degradation.
Q3: Can I use this bit for finishing cuts?
This bit is optimized for roughing. For a smooth final surface, switch to a dedicated finishing bit.
Q4: Is it compatible with all CNC routers?
Yes, as long as the shank matches your router’s collet size. Common sizes like 8mm, 12mm, and 1/2" are widely compatible.
Q5: How long will it last?
With proper use and maintenance, the TiN-coated solid carbide bit can last 3× longer than uncoated tools under similar workloads.
