Anton & Chheda Design SV6 Advanced Carbide Chamber Drill Bits by Yu Xuanjie Full Taper V
Yu Xuanjie ToolsFor Advanced users of Freehand drilling, or others in a hand drill, and lathe or drill press. These can be used as a double bladed spoon bit. Due to the recessed backing, both blades will cut faster than a single blade spoon bit. No pilot hole is needed. Due to the double blades, there is a little more risk of grabbing than a single blade spoon bit. We highly recommend to only use these as freehand drilling if you have advanced experience freehand drilling.
These bits can be used in a power hand drill, lathe tailstock, or drill press chuck. No pilot hole is needed to drill.
Bonus* If you only have a Power hand drill, these are the only chamber bits that can drill directly into a secured block. Machinery is not needed!

22mm: Diameter at largest area: 22mm Length of cut: 60mm

SV6 advanced carbide
I have several A&C / YU carbides, these guys must be tired. Research n development continues to improve; the ease (low pressure needed for hole expansion) and cleanliness (results). Your drills and tobacco will thank you.
