Perfect for my cnc. ### ⭐⭐⭐⭐⭐ Review with Speeds and Feeds *by on Reviewed in the United Kingdom 5 January 2025* I purchased the bit set for machining small text on hardwood (Mahogany and light Oak) and epoxy. I had tried using 20 degree V-bits but found that due to the small step over there was quite a lot of manual clean up to do and was limited in the depth of cut as cutting any deeper than a 1.5mm lead to the middle of the "e, 4 and o" breaking off. So decided to try tapered Ball Nose bits.I have a Foxalien WM3020 with a 720W spindle and fully expected to snap the two smallest bits, but was pleasantly surprised when the cuts came out perfect and captured the detail I was unable to get with the V-Bits and with virtually no clean up. I did a lot of research on the speeds, feeds and depth of cut for each bit for my spindle which will cut up to 30,000 rpm and set all my speeds, feed and depth of cut to the absolute minimum recommended for materials.Will definitely purchase again.If you cut and paste the following in to ChatGTP it will generate a table with all the speeds and feeds for a 300W spindle with max 10,000 RPM. I must stress that I have NOT done any machining with my 300W spindle.Provide speeds, feeds, and depth of cut table for Genmitsu TB04A tapered Ball Nose Endmill set for cutting Hardwood, softwood, MDF and Aluminium when using a 300W spindle that has a max speed of 10,000 RPMBit specifications are:Material: Tungsten Carbide Steel AlloySurface : Nano Blue CoatingRadius: R0.25, R0.5, R0.75, R1.0mmShank Diameter: 3.175mmCutting Length: 15mmOverall Length: 40mmGood luck ### ⭐⭐⭐⭐⭐ Tooling *by on Reviewed in the United Kingdom 20 March 2026* Good all round tooling ## Frequently Bought Together - Genmitsu 4pcs 2-Flute Tapered Ball Nose End Mills Tungsten Carbide Cutter with Nano Blue Coat, R0.25-1.0, 1/8” Shank, TB04A - SainSmart Genmitsu 10Pcs Nano Blue Coat Flat Nose End Mill CNC Router Bits, 1/8" Shank Spiral Upcut 2 Flute End Mill Set (3.175 x 17 x 38mm) - Genmitsu 10 Pcs 1/8" Shank V-Groove CNC Router Bits, 10 /15 /20 /25 /30 /40 /45 /60 /90 Degree Set, Nano Blue Coat Conical V-Bit, Engraving Tool for CNC Signmaking Carving Lettering 2D&3D Sculpture --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tw/products/238836912-tapered-ball-nose-end-mill-set](https://www.desertcart.tw/products/238836912-tapered-ball-nose-end-mill-set) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-09-23*
