Yougfin Cobalt Drill Bits, M35 High Speed Steel Drill Bit Set with Round Straight Shank, 135° Split Point, Double Fluted, 15Pcs

  • 【Application & Tip】: Yougfin Jobber Drill Bit are ideal for sheet metal working and are suitable for cutting non-ferrous metals, plastic, wood board, etc. ***Tip***:Please keep the bit perpendicular to the mateial during operation to prevent it from breakage. If you have any questions about Yougfin products, please feel free to contact us
  • 【Dual Flutes】: Twist drills are rotary cutting tools that have two cutting edges and two flutes which are grooves formed in the body to provide cutting lips, to permit the removal of chips and to allow coolant or cutting fluid to reach the cutting action
  • 【M35 HSS+5% Cobalt】: Yougfin drill bits are made of M35 High Speed Steel with 5% Cobalt added, which is much harder than typical HSS and thus suitable for precision drilling in stainless steel and other hard materials. What's more, cobalt blend gives these bits a much longer life
  • 【135° Split Point】: These metal drill bits have a small point angle of 135° and require less pressure when centering in the material. The point starts drilling at contact, reducing friction, pressure, and heat. The larger the point angle, the higher the contact pressure and the centering in the material requires more pressure
  • 【Operation Technique】: When drilling a hole with a cobalt bit, add a drop of oil on the metal to keep the cutting edge cooler as it cuts. You also want to consider placing some wood underneath the steel if possible. This lets you cut cleanly through the material and not strike a surface below which might dull the cutting edge

Factors to Keep in Mind When Buying cobalt drill bit

We have prepared a list of guidelines to help you make an informed choice when buying cobalt drill bit online.

Know your needs

Before buying cobalt drill bit online, ensure you know exactly what you need and what your money should buy. For example, if you're looking for an anti-aging cream but don't have any wrinkles yet, don't waste money on this type of product until it's really necessary! It is important to know your problems with each purchase and whether the benefits outweigh their costs.

Do your research!

You've probably heard this advice before, but it's still true: never buy cobalt drill bit without reading reviews or doing some research first! The Internet makes it very easy to find honest opinions about almost any product on the market today; don't hesitate to read them before buying cobalt drill bit

Check the seller's return policy.

Make sure you know the seller's return policy before making a purchase. You may find that some sellers have policies that allow customers to return their products within 30 days of purchase or even 60 days if they're not satisfied with their purchase. This is especially important for large purchases like furniture because once it's delivered and assembled, it can be difficult to transport and return if needed.

Buy from a well-known brand.

If you have your heart set on a particular brand, that’s the best product. For example, if you want to buy a Samsung S9 phone, you should shop for it online at the Samsung website or any other Samsung store.

Check the shipping options.

If you are ordering an cobalt drill bit online, make sure that the website offers free shipping so that you don’t have to pay cobalt drill bit extra after making your purchase. If there is no free shipping option, consider purchasing from another website that offers this service.
