Review: Always reliable and holds an edge - So much better than the less expensive bits I’ve always purchased. Review: Very good bits and great material. - The only type of bit to use for Stainless and use it on a VERY low speed with plenty of cutting fluid. Never use a hammer mode with these. Treat them well and you'll only rarely need to sharpen them. ## Features - Visible clear lid of the drill bit set are desgined for easy viewing of contents - Stackable - for convenient travel and storage - Accessible - for customizable kits - Redesigned tip helps promote long life - Three-flatted shank design ideal for keyless chucks ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0000EI9AZ | | Best Sellers Rank | #208,352 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #445 in Jobber Drill Bits | | Brand Name | IRWIN | | Customer Reviews | 4.6 4.6 out of 5 stars (359) | | Cutting Angle String | 135 Degrees | | Finish Types | Cobalt Alloy Steel | | Global Trade Identification Number | 00024721063625, 20024721063674 | | Included Components | ......... | | Item Dimensions | 10.25 x 10.94 x 11.06 inches | | Item Type Name | ........ | | Item Weight | 11.2 ounces | | Manufacturer | IRWIN | | Material Type | Cobalt | | Model | 316015 | | Number of Flutes | 2 | | Point Style | Split Point | | Shank Type | Straight | | Surface Recommendation | Abs,Cast Iron,Metal,Metals,Stainless,Steel | | Tool Flute Type | Spiral | | UPC | 069060287837 735090394318 643749770553 788809213707 640024962856 044112272108 051020079149 024721063625 636123632158 024721063670 031113019610 100028845994 971489884385 | | Unit Count | 1.0 Count | | Warranty Description | Manufacturer | ## Product Details - **Brand:** IRWIN - **Cutting Angle String:** 135 Degrees - **Finish Type:** Cobalt Alloy Steel - **Material:** Cobalt - **Shank Type:** Straight ## Images ![Tools IRWIN Drill Bit Set, Cobalt Alloy Steel, 15-Piece (316015) - Image 1](https://m.media-amazon.com/images/I/61aHcRuVDXL.jpg) ## Questions & Answers **Q: These are NOT 8% Cobalt?** A: Amazon is shipping the 3018002 (5% cobalt) in error and not the 3018002b (8% cobalt) as listed in their product title and description.
