I could not use my cordless drill as the chuck was too small but it fit my standard electric drill with no problem. Handy little tool that I will keep on my tool box for other jobs. Review: Decent cone cutter - Usually use G&J Hall cone cutters which are outstanding, but very expensive. For the price this is very good quality, and works well. It doesn't open up as quick or as cleanly, compared to the hall ones but im happy with it. Rusts quickly if you get it wet, so keep it dry ## Features - The HSS step drill bit is made of high quality steel and coated with titanium to reduce the friction and heat. - You can use it with many different materials such as steel, brass, wood, plastic, copper, fibreglass and PVC - The holes are very clean and precise, and for best results and for different sized holes, only a drill is required. Drill anything from 5 to 35 mm - The drill sizes are clearly lasered on, to make precise drilling easy. - During the work of the step drill you pour water, can extend the lifetime effectively. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01KRDFK6I | | Best Sellers Rank | 345,598 in DIY & Tools ( See Top 100 in DIY & Tools ) 138 in Step Bits | | Brand | VAKKI | | Customer Reviews | 4.1 4.1 out of 5 stars (4,987) | | Cutting Angle String | 118 Degrees | | Cutting Diameter | 5 Millimetres | | Finish Types | Aluminium, Titanium | | Manufacturer | Vakki | | Material | High Speed Steel (HSS) | | Number of Flutes | 2 | | Point Style | Step Point | | Shank Diameter | 6.35 Millimeters | | Shank Type | Straight | | Surface Recommendation | Metal, plastic, wood | | Tool Flute Type | Spiral | | UPC | 745950547488 | | Unit Count | 1 count | ## Product Details - **Cutting diameter:** 5 Millimetres - **Finish type:** Aluminium, Titanium - **Material:** High Speed Steel (HSS) - **Shank diameter:** 6.35 Millimeters - **Shank type:** Straight ## Images ![Audel professional HSS step drill UniBit, diameter 5-35 mm titanium, 2 cutting edges - conical drill bit - conical drill silver - Image 1](https://m.media-amazon.com/images/I/51qdWbpICaL.jpg) ![Audel professional HSS step drill UniBit, diameter 5-35 mm titanium, 2 cutting edges - conical drill bit - conical drill silver - Image 2](https://m.media-amazon.com/images/I/41VCGu7hxiL.jpg) ![Audel professional HSS step drill UniBit, diameter 5-35 mm titanium, 2 cutting edges - conical drill bit - conical drill silver - Image 3](https://m.media-amazon.com/images/I/41Hqzgcpf5L.jpg) ![Audel professional HSS step drill UniBit, diameter 5-35 mm titanium, 2 cutting edges - conical drill bit - conical drill silver - Image 4](https://m.media-amazon.com/images/I/61vO6vLH7ML.jpg) ![Audel professional HSS step drill UniBit, diameter 5-35 mm titanium, 2 cutting edges - conical drill bit - conical drill silver - Image 5](https://m.media-amazon.com/images/I/61uqEzLTiGL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great wee tool , did the job *by F***9 on 23 April 2018* Bought to use on plastic to make an existing hole bigger it worked a treat it was so easy.

Handy little tool that I will keep on my tool box for other jobs. ### ⭐⭐⭐⭐ Decent cone cutter *by E***R on 30 December 2018* Usually use G&J Hall cone cutters which are outstanding, but very expensive. For the price this is very good quality, and works well. It doesn't open up as quick or as cleanly, compared to the hall ones but im happy with it. Rusts quickly if you get it wet, so keep it dry ### ⭐⭐⭐⭐⭐ Unbelievable price for this quality. Ideal addition for the toolbox. *by M***P on 12 May 2019* For the price this is bloody fantastic. So far I have used it to enlarge a hole in a plastic dashboard panel to 27mm and also to enlarge the mounting holes for a safe from 8 to 12mm. Plastic capable - Check 3mm steel panel capable - Check The cutter shows no sign of wear after either task. The hole it made was nice and clean in the plastic, metal may need some deburring afterwards as the cutter can leave some swarf attached to the workpiece. There is not a lot of tolerance between the steps so this tool will not be any use for thick materials. Anything more than 3mm will require drilling from both sides to obtain an even aperture or you'll end up with a cone shaped hole. You’ll need at least a 1/2” chuck on your drill to fit this bad boy in, the shank is chunky. Take the job nice and slow to avoid snagging or over drilling the hole too big. Remember, you can’t drill a bit back on. ## Frequently Bought Together - Step Drill Bit, Vakki HSS Double Slot Cone Cutting Drill (5mm-35mm) with Titanium Coating -Silver - Starrett HSS Bi-Metal Hole Saw - FCH0100 Fast Cut Extra Cobalt Hole Saw - For Stainless Mild Sheet Wood Plastic Various Materials - 25mm --- ## 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.ec/products/55337363-audel-professional-hss-step-drill-unibit-diameter-5-35-mm](https://www.desertcart.ec/products/55337363-audel-professional-hss-step-drill-unibit-diameter-5-35-mm) --- *Product available on Desertcart Ecuador* *Store origin: EC* *Last updated: 2026-04-22*
