Titanium is universal in many drill bit coatings mainly for increasing tool life and wear-resisting quality. It increases cutting speed and can be used for drilling in any metal type, including non-ferrous metals, whereas black oxide can be used in certain materials. Black oxide reduces friction and does not allow heat while drilling, and increases chip flow up and out of the drill, making the drilling process clean and smoother.

Drill Bit Coatings

Drill bit coating plays an essential role in increasing durability and faultless working. There are many types of drill bit coatings. Titanium nitride, titanium carbonitride, and black oxide coating is widely used to maintain the product anew for a longer period, resisting heat and rust, and are best for softwood, hardwood, fiberglass, and steels. Some coating looks bright, but they are not real finish but assist in increasing chip flow.

Metal Drill Bit vs Wood

Metal drill bits intended to cut through tough materials, but wood drill bits cannot cut only wood and light materials. Either using metal bits in wood or wood bits on metal results in the abrasion of materials. Metal drill bits have an angled tip where wood comprises brad, a sharp tip to snag wood. Wood drill bits are often in silver, with Metal Cutting Drill Bit with titanium or black oxide coating.

  2. Many sharpener brands remove dull pieces and provide a sharpened edge.
  3. Bench grinders with two grinding wheels assist you where some prefer doing in hands.
  4. The chisel edge must angle at 55 degrees to the main cutting edge.

How to Take Care of Your Bits?

  1. Make sure you drill the right material designed for your drill bit.
  2. Fix it rightly in the chuck of adaptable drillers or drivers to resist damages.
  3. Make certain bit sizes tightly fixed in the lid at appropriate places after using it.
  4. Lubricating bits reduce friction and give longer life. Store it in a container case to get rid of corrosion.

How to Drill Stainless Steel?

  1. Right drill bit intended to drill stainless steel should be used for drilling.
  2. The drill bits for stainless steel should be satisfied as high-speed steel and recommended to use bits sizes to hole size you need.
  3. Cobalt drills would be a worthy investment for those who work extensively in stainless steel.
  4. The split point of drill bits should have cutting angles of 135 degrees to make thinner chips for easy elimination.

Tips for Drilling Holes in Metal Using Drill Bit

  1. Lubricated bits gives longer life
  2. Wear safety glasses to protect your eye from tiny metal fragments
  3. Make a dimple with center punch to prevent walking
  4. Clamps help by holding down the metal piece and makes drilling easier
  5. Always start with a small hole with a small bit size that helps drill larger holes accurately
  6. Deburr the hole by slightly taking out a bit from drilled level to clean out burr and debris
  7. Drill at a slow speed to reduce heat and get an expected hole

Troubleshooting Guide for Metal Drill Bit

Use wider flute drill bits if flutes get clogged with chips in deep holes. Further polished flutes would help more in clearing out chips and make drilling easier. Holding drill bits in hands will be insecure, so use clamping devices or holders to get fixed tightly to restrain walking or slipping. In case of drill bit dulling, check speeds and feeds and no.5 premature dulling. Having additional care over bits by using appropriately would improve its durability.

What Type of Drill Bit Do I Need for Metal?

Drilling is not easy on metals, unlike other materials. Various types of metals and drill bits are intended with a unique structure to drill in certain material types only. Most of the drill bits satisfy the needs of both ferrous and non-ferrous materials. It is a prime duty for anyone to clearly understand their needs and how well the product satisfies you. Drill bits for metal come with many ergonomic designs, quality, coating, and performance features.

Things to Consider While Buying a Drill Bits for Metal

Drill bits are a common tool to be kept in the home and compulsory for project workers, HVACs and repair persons. Before buying the drill bit, you should be aware of the drill bit required for your project. You should look at its material quality, shank type, durability effects, and performance, adding to cost worthiness.

Drill bit material

Most drill bits are made of high-speed steel, cobalt, and carbide materials, depending on the durability and compatibility. It is imperative to examine the best drill material that aptly suits your project needs. These varieties of material standards keep on varying in their price, adaptability, and performance too. High-speed steels act as a multi-purpose drill bit that is inexpensive and widely used for ferrous and non-ferrous. Cobalt works efficiently in heavy materials but not in soft metals. Carbide metal-drilling bits made from carbide are highly compatible with tough materials. Both cobalt and carbide are expensive for their heavy working range.

Coating

Coating matters a lot in drill bits as a strong coating surface highly protects the material. Effective Coating not only keeps it looking new but maintains quality and sturdiness. Most drill bits come with titanium or black oxide coating. While reviewing various drill bits, we encountered most drill bits that are titanium coated as it gives much life and increases cutting speed. The black oxide coating is equally effective in reducing heat and eventual breaking. Appropriate Coating saves a life for drill bits while meeting any hard surfaces. Don’t get fooled by attractive colors but also go through the coatings of your drill bit and purchase accordingly.

Shank Design

The shank design is the non-drilling part of the drill bit that fits into the chuck or drill mandrel. It is necessary to know shank type in your drill bit as the shank size of the bit plays a greater role in effective drilling. Ensure it fits well in your preferred drill chuck because improper fixation would damage the bit and give a poor experience. Drill bits mostly come either as no-spin or hex shank type that secures smooth drilling and prevents the surface. No-spin shank offers extensive benefits by preventing the bit from slippage and walking, whereas hex shank has six sides that aids in keeping the bit steadier while drilling into hard metals.

Pricing

Adding to all futuristic qualities, spending on a product that values our money is crucial. It is not always that expensive products give ultimate satisfaction. We have enjoyed ultimate service from low-cost devices that are highly capable than costly ones. Drill bits prices are normally at a low budget, but it increases depending on brand and designs. The prices of drill bit models vary with the number of pieces provided in the package. Coatings, shank type, and anti-walking features further add bucks to its pricing. Revise all the varieties and choose the one that fulfills your needs at an affordable value.

Warranty

From our review, we realized the drill bits design gives a clear idea about its guarantee period. High-speed steel naturally increases durability, and carbide ensures break-free working on heavy materials. Warranty is essential to consider while buying because you can’t lose money on a failed product or damage your surface. Most drill bit companies don’t provide warranty except a few renowned brands that rely on customer satisfaction and durable performance. To put your knowledge, a warranty for drill bits can’t be expected for more than 1 year.
