Description of HUAZHICHUN Straight πŸ’ͺ Stainless: Unparalleled Strength and Durability

COBALT STEEL - Manufactured from M35 cobalt steel, with molybdenum and cobalt added to creates a hardened alloy, measuring Rockwell hardness up to 67, extremely heat resistant; for much faster cutting and extra longer life span, with up to twelve times when compared with an average HSS drill bit. NO CENTER PUNCH NEEDED - The 135Β° Quick-Cut points are self-centering and penetrate quickly with less pressure. Will not "walk" or "wander". Straight shank allows for firmly holding and accurate centering, fit for standard drill chucks and regular round collet chucks. Must be used and operated at proper RPMs for maximum efficiency. 13PC METRIC BITS - The set includes 13pcs of M35 cobalt steel twist drill bits: 1.5mm, 2mm, 2.5mm, 3mm, 3.2mm, 3.5mm, 4mm, 4.5mm, 4.8mm, 5mm, 5.5mm, 6mm, 6.5mm. FOR METALWORKING - Particularly successful in cutting through hard metals such as stainless steel and cast iron, although they can be used for softer materials, too. SATISFACTION GUARANTEED - we do care about your satisfaction. We try our best to ensure each product is in perfect condition before you get it, but if something is not up to your satisfaction, please contact us for a full refund or replacement.

Perfectly straight, decent storage box, undeniable value.

They are very well made. I've thrown them in a drill to check for vibration as they spin and it returns zero. Very impressed with the price. And the steel case is included? Outside of Revain I've seen similar items in a store for double the price.

I love this set! on Electric Drill Parts & Accessories

The drill bits are really strong and feel good in my drill press. I'm an artist and I'm in the process of expanding my range of Christmas decorations and this set will be very useful to me. I really like that they come in a nice metal case that keeps them all organized and easily accessible. Comes in any size I need. Excellent purchase!

Chips the first time you drill with brass

Your mileage may vary. But I was surprised when the tip broke off on one side and punched a hole through the brass. There was no lateral movement, it was in the drill press, properly aligned with the part held securely in a vise. This was also the very first use of this drill. If this happens with brass, I highly doubt these bits can work with hardened steel as they claim. The price is good, but buy at your own risk.
