What is the Difference Between the 8-Piece and the 12-Piece Set?

Both sets include:

• 30° Solid Carbide Spektra™ Engraving
• 90° In-Tech Insert Carbide V Groove
• Spektra™ 2D and 3D Carving 5.4 Deg Tapered Angle Ball Nose
• 2 Spektra™ Spiral Flute Plunge downcut bits (different ones)

The 12-piece set adds:

• Spektra™ 3.6 Deg Tapered Angle Ball Nose
• Spektra™ 0.10 Deg Straight Angle Ball Nose
• Carbide Tipped V Groove 60 Deg (not Spektra™)
• Core Box Bit
• Spektra™ Mortise Compression Spiral 
• Point Cutting Roundover Bit
• Spoilboard Surfacing & Flattening 3-Flute Router Bit

The 8 piece set includes a Spektra™ Spiral Flute Plunge upcut bit and a Spektra™ compression bit (not the Mortise Compression, a different one), plus the 60° Insert V-Groove Router Bit, not included in the 12-piece set.

For serious signmakers, you'll either want the 12-piece set or you'll want to supplement the 8-piece set with additional bits.

We also have signmaking sets designed specifically for work with plastic or aluminum & stainless steel. 

Long lasting insert knives provide superior, smooth quality cuts every time. Insert tooling allows for harder grades of carbide & is a cost-effective solution compared to replacing brazed router bits. 

Each V Groove router bit comes complete with solid carbide insert knife/knives designed with unique grinding angles to eliminate build up at the V point.

Usage Tips

Start by testing your bits on scrap material, especially when trying out new fonts or layouts. Use shallower depths for fine lettering to avoid blowout. For best results:

• Secure your material tightly to prevent shifting
• Use the correct feed rate for each bit size
• Let the bit do the work—don’t force it
• Keep your bits clean and sharp to prolong life

Software and Training

New CNC signmakers will benefit from using Vectric VCarve and VCarve Pro software, which simplifies layout and toolpath creation. It pairs perfectly with the Spektra bit sets mentioned above.
