Best Zinc Jobber Drill Bits in 2026

★【Premium Bright Finish 2/Pack】 multi-purpose solid carbide drill bits provide better rigidity than high speed steel bits. It is extremely heat resistant and used for high speed applications. Our tungsten carbide (WC) bits has the advantage of cutting metal either "wet" or "dry" and they provide solutions for many businesses such as aerospace drilling jobs for aircraft mechanics, precision machining, hobby supply, etc.

★【Recommended For Use On】 aircraft metals chrome titanium inconel stainless steel Alloys Steel Low-Medium-High Carbon Steel Aluminum Copper Glass Plastics Composite Materials Cast Iron -- Our Carbide drills stay sharp many times longer than traditional steel bits making them ideal for the toughest of applications!

★【Optimal Design for Metal Work】 118° four facet point angle minimizes drill wander and assures accurately sized holes. Our jobber length, precision ground carbide drills are designed for high feed rates with good chip disposal. smooth finish on the bits increases chip flow. Spiral flutes are constructed with a higher flute angle to remove chips more easily.

DRILL HOLES EASILY – Push down the handle to rotate the bit and when stopped the bit springs back counterclockwise – essentially self-clearing

RETRO TOOL – This non-electric and environmentally friendly drilling option will bring some sentimental feelings while performing small job ideally

8 DOUBLE FLUTED BITS – Conveniently store inside the handle and includes sizes 1/16, 5/64, 3/32, 7/64, 1/8, 9/64, 5/32, and 11/64 inch

Material: YG Cemented Carbide + Chrome Vanadium Steel. Ideal for drilling in tough metal, including heavy-duty abrasive alloy metal drilling on hardened steel.

The mistake that a lot of people make is using high speed steel twist drills at high speeds. If you search for "machining speeds and feeds" you will find a lot of information about the correct speeds to run cutting tools against different types of metal. Twist drills are the category of cutting tool you are looking for.

As soon as the heat starts to build up on the tip, the drill bit can lose the hardness that make it a cutting tool. Using HSS drills at low rpm with cooling fluid or lubricant can provide a large quantity of successful holes in metal. TThere have chunks of carbide on the end, and carbide will make easy work of even the hardest steel, and allow you to use high rpms. (In the process of opening holes to continue to add water for cooling.)
