Review: Worth the money - Boy oh boy am I glad I bought this step bit over the cheaper ones I was considering. I needed to cut a bunch of different sized holes in a 1/4-inch-thick piece of hard aluminum, which I'm using on a home-built router table. I initially looked at other cheaper unibits that claimed to be made of cobalt or titanium, but I learned long ago that you can't go cheap when it comes to tools. You always get what you pay for, especially when it comes to tools. But this bit cost five times that of the cheaper ones, so it was not an easy decision. This bit arrived on time and came in a nice plastic storage case. It was well-oiled and quite sharp. Its quality is noticed the moment you pick it up and feel its solid weight. Drilling the holes was like using a hot knife through butter. Using the "1" speed on my power drill, I was able to completely bore through the aluminum within about a minute or two. The bit remained cold to the touch immediately after drilling several holes. The flutes/blades still remain very sharp with no signs of chipping or marring. Do not waste your time and money with the bargain bits. Get this one and use it for a lifetime. ## Features - M35 cobalt step drill, 1/4" (6.35mm) hex shank, 2 holes: 7/8" (22.22mm) and 1-1/8" - 2 HOLE SIZES: 7/8" (22.22mm) and 1-1/8". The size marks are stamped next to each step for easy identification. - DOUBLE SPIRAL FLUTES: For more efficient swarf clearance; 1/4 inch hex shank with quick release slot to eliminate slipping; Self-starting for clean holes in thin materials; M35 cobalt HSS to cut stainless steel. The step drill bit is made with M35 cobalt. Ideal for a variety of materials from stainless steel, metal, plastic, fiberglass to wood. They also help to enlarge existing holes. M35 HSSCo is a high speed steel alloy made up of 5% cobalt. M35 is similar to M2, but with 5% cobalt added. - M35 COBALT: The addition of cobalt increases heat resistance. It is widely used in metal manufacturing because of its ability to resist wear over conventional high speed steels, allowing for shorter cycle times in production environments due to higher cutting speeds or from the increase in time between tool changes. M35 is also less prone to chipping when used for interrupted cuts. - US-BASED CUSTOMER SERVICE: Available by chat, email, phone, or visit us at our customer service center in La Crosse, WI. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00IQJKM14 | | Best Sellers Rank | #8,925 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #16 in Step Drill Bits | | Brand | TEMO | | Brand Name | TEMO | | Customer Reviews | 4.7 out of 5 stars 110 Reviews | | Cutting Diameter | 1.13 inches | | Finish Type | Uncoated | | Finish Types | Uncoated | | Item Dimensions | 3 x 1 x 1 inches | | Item Highlight | Spiral Flute Unibit| Single-Pass Large Hole Drilling| Fast Auto Chip Removal| Fit Dewalt Milwaukee Bosch Makita | | Item Weight | 6 ounces | | Item dimensions L x W x H | 3 x 1 x 1 inches | | Manufacturer | Golden Coulee | | Material | Cobalt | | Material Type | Cobalt | | Minimum Bore Diameter | 0.63 inches | | Number of Flutes | 2 | | Number of Packs | 1 | | Number of Pieces | 2 | | Part Number | 1527 | | Set Name | Two Size: 7/8 Inch and 1-1/8 Inch | | Shank Type | Hex | | Surface Recommendation | Fiberglass, Metal, Plastic, Wood | | Tool Flute Type | Spiral | | UPC | 723175193413 | | Unit Count | 1 Count | ## Product Details - **Brand:** TEMO - **Cutting Diameter:** 1.13 inches - **Finish Type:** Uncoated - **Material:** Cobalt - **Shank Type:** Hex ## Images ![TEMO M35 Cobalt Step Drill Spiral Flute, Two Size: 7/8 Inch and 1-1/8 Inch - Image 1](https://m.media-amazon.com/images/I/61t-oRUnWQL.jpg) ![TEMO M35 Cobalt Step Drill Spiral Flute, Two Size: 7/8 Inch and 1-1/8 Inch - Image 2](https://m.media-amazon.com/images/I/71Flspdp-BL.jpg) ![TEMO M35 Cobalt Step Drill Spiral Flute, Two Size: 7/8 Inch and 1-1/8 Inch - Image 3](https://m.media-amazon.com/images/I/61SWmRQX4+L.jpg) ![TEMO M35 Cobalt Step Drill Spiral Flute, Two Size: 7/8 Inch and 1-1/8 Inch - Image 4](https://m.media-amazon.com/images/I/61+S3vZx-ZL.jpg) ![TEMO M35 Cobalt Step Drill Spiral Flute, Two Size: 7/8 Inch and 1-1/8 Inch - Image 5](https://m.media-amazon.com/images/I/71+USq2e-1L.jpg) ## Available Options This product comes in different **Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ fast cutting and durable, excellent for electrical work. *by R***D on August 27, 2026* faster than a knock out punch , but use carefully , or youll end up with a larger hole than you want. ### ⭐⭐⭐⭐⭐ Worth the money *by W***S on August 10, 2018* Boy oh boy am I glad I bought this step bit over the cheaper ones I was considering.
