The IRWIN 316015 15-Piece Cobalt HSS Drill Bit Set is engineered for high-performance drilling in tough, high-tensile materials such as stainless steel, cast iron, and hardened steel. Constructed from premium M-42 cobalt high-speed steel with a black oxide finish, these bits offer superior heat and abrasion resistance for extended tool life. The 135-degree split point tip ensures precise starts by preventing walking and reducing the required feed pressure. This professional-grade set includes fractional sizes ranging from 1/16" to 3/8" and is housed in a durable, impact-resistant ABS storage case with rubber over-molding for maximum jobsite protection.

Constructed of M-42 8% cobalt high-speed steel for super abrasive resistance in tough metals. Bits have a 135 deg split point which reduces feed pressure for easier penetration. Includes (2) 1/16 in, (2) 5/64 in, 3/32 in, (2) 7/64 in, 1/8 in, (2) 9/64 in, 5/32 in, 3/16 in, 7/32 in, 1/4 in, 5/16 in, 3/8 in and (1) rubber-sided case with sliding latch for added security.

General Ledger Coding

General Ledger Coding is a value added service provided for you at no additional cost.

General Ledger Coding makes accounting easier by providing you with a calculated total of purchases based on your General Ledger Codes.

In addition to traditional General Ledger Summary provided at time of invoice, we can also provide quotes and order acknowledgements with General Ledger Coding as well. We also give you the ability to change a GL Code for one or all items for renovation projects that may utilize a single GL Code. We can also code any of our "extended inventory" items with your General Ledger Code at the time of quote, order confirmation and invoicing as well. We can code our item numbers directly to your GL Codes should our item categories not align directly with your GL Code Categories.

Please contact us if you wish to implement our General Ledger Coding feature.
