IRWIN Tools Cobalt Alloy Steel High-Speed Steel Drill Bit, 29-Piece Metal Index Set (3018002). desertcart.com The Irwin 29-Piece Cobalt M-35 Metal Index Drill Bit Set includes drill bit sizes measuring from 1/16 to 1/2-inch in 1/64 inch increments. The 29 bits are made using heavy duty web construction for strength and durability, and the cobalt steel extends the life of cutting edges. The 135-degree split point tips start drilling on contact and cut with less force. A reduced shank above the 3/8-inch point lets you use larger drill bit in a 3/8-inch chuck, and you can select the right bit using a convenient tap and drill selection chart. The set's rubber overmolded case protects against damage from accidental dropping, and you can remove cartridges to easily carry bits from the case to your worksite. Review: Cuts well, clean and faster than cheaper drill sets - Have historically bought and used cheap bits. Decided to try something different. These cost more but are well worth to money to me. Have drilled, steel, aluminum and wood. So much less frustrating to use these than the cheapies I previously bought. The one complaint is the box does not align and closes as well or easily as it should. I still gave it 5 stars based on the bits cutting ability. Also I have not tested for durability as I am not frequent user. Review: Does the job - Drill bits that can drill. Plenty sharp after our old set were worn down by use. ## Features - 29 Piece - Cobalt Alloy Steel Drill Bit Set - Sizes 1/16 inch -1/2 inch in 1/64 inch increments, 135 Degree Split Point To Minimize Walk - 5% Cobalt Alloy Steel For Higher Heat & Abrasion Resistance - Heavy Duty Web Construction For Strength & Durability ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000BO9JMK | | Best Sellers Rank | #104,047 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #196 in Jobber Drill Bits | | Brand | IRWIN | | Brand Name | IRWIN | | Customer Reviews | 4.7 out of 5 stars 1,074 Reviews | | Cutting Angle String | 135 degrees | | Cutting Diameter | 1.59 millimeters | | Finish Type | Cobalt Alloy Steel | | Finish Types | Cobalt Alloy Steel | | Global Trade Identification Number | 00024721065131 | | Included Components | 29PC DRILL BIT INDUST SET CASE COBALT | | Item Dimensions | 11.6 x 12.3 x 3.4 inches | | Item Type Name | 29PC DRILL BIT INDUST SET CASE COBALT | | Item Weight | 0.27 g | | Manufacturer | IRWIN | | Material | Cobalt | | Material Type | Cobalt | | Minimum Bore Diameter | 0.06 inches | | Model | 3018002 | | Number of Flutes | 2 | | Number of Packs | 1 | | Number of Pieces | 29 | | Part Number | 3018002 | | Point Style | Brad Point | | Set Name | 29-Piece | | Shank Type | Split Point | | Surface Recommendation | Alloy Steel | | Tool Flute Type | Spiral | | UPC | 024721065131 072090456609 013317064573 640026835608 247210851538 031112513171 643749770621 024721631381 640024789705 013588056437 031113081044 971473194087 024721085153 787721785538 080850305630 735090418502 732454799673 971473194070 | | Unit Count | 1 Count | ## Product Details - **Brand:** IRWIN - **Cutting Angle String:** 135 Degrees - **Finish Type:** Cobalt Alloy Steel - **Material:** Cobalt - **Shank Type:** Split Point ## Images ![IRWIN Drill Bit Set, M35 Cobalt Alloy Steel Steel, 29-Piece (3018002) - Image 1](https://m.media-amazon.com/images/I/61pYtPUyr6L.jpg) ## Available Options This product comes in different **Size, Style** options. ## 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.
