Frequently Asked Questions
Q: What is the shank size of these left-hand router bits?
A: These router bits feature a standard 1/8-inch (3.175 mm) shank, making them compatible with most CNC machines and handheld routers that accept 1/8-inch collets.
Q: Why would I use left-hand spiral router bits instead of standard right-hand bits?
A: Left-hand spiral router bits cut in the opposite rotational direction, which is ideal for certain CNC setups and routing applications where you need downward chip ejection or cleaner top-surface finishes on specific wood types. They help minimize tear-out on the leading edge.
Q: Are these router bits suitable for use with hobby CNC machines?
A: Yes! The 1/8-inch shank is a common standard for desktop and hobby-grade CNC routers, as well as many professional CNC machines. Always verify your machine's collet size before use.
Q: What materials can I cut with these HSS milling cutter bits?
A: These high-speed steel bits are optimized for woodworking tasks including softwood, hardwood, MDF, plywood, and similar wood-based materials. They are designed specifically for wood carving, edge trimming, and detail work.
