The drill point angle refers to the angle at which the cutting edge of the drill bit is ground. It is measured in degrees and can range from 90 to 150. A 118-degree angle is the most common, but other angles, such as 135 degrees and 90 degrees, may be more suitable for specific materials or applications.Common Drill Point Angles

Cobalt (HSCO) drill bits are made from high-speed steel with added cobalt, which enhances their strength and heat resistance. They can withstand higher temperatures and are less prone to dulling. Cobalt drill bits are ideal for drilling through hard metals, such as stainless steel, cast iron, and titanium.

BRAMPTON, ON –  CUPE Local 831 and the City of Brampton have reached an agreement to end a nearly week-long strike that saw 1,200 workers on picket lines across the city.

To choose the best drill bits for metal and other materials, you should consider the design features that affect their performance. These are the three key design features of drill bits:

A bare metal finish with no coating. It is the most common type of drill bit. They are best used for drilling plastic, wood, and soft metals.

“This strike was a last resort that unfortunately interrupted many services that residents depend on. We thank all residents of Brampton for their patience and support during the strike and to everyone who showed their solidarity with us on the picket line. Our members look forward to returning to work soon to continue serving Brampton residents.”

A gold-colored coating that provides heat resistance and hardness. It is made by depositing titanium nitride on the surface of the drill bit.They are best used for drilling hard materials such as stainless steel, cast iron, and titanium.

High-speed steel (HSS) is a type of tool steel that is highly resistant to heat and wear. It contains tungsten, molybdenum, chromium, and vanadium, which provide increased strength and durability. HSS drill bits are suitable for drilling into soft metals, such as aluminum and brass, as well as wood and plastic.

“From the beginning, we have said that this strike was about fairness for our members and reaching a deal that is comparable to what others who work at the City of Brampton have received and we have been able to reach an agreement that achieves that” said CUPE 831 President Fabio Gazzola. “This agreement will help our members deal with the increased cost of living they’re facing and recognizes the work that they do.”

A gray-colored coating that is harder than TiN. It is made by depositing a layer of titanium carbonitride on the surface of the drill bit. They are best used for drilling abrasive materials like high-silicon aluminum, fiberglass, and carbon composites.

Each type of drill bit has its own unique features, suitable applications, advantages, and disadvantages. Choosing the right type of drill bit is essential for achieving accurate and efficient results in drilling.

Flutes are the grooves that run spirally along the length of a drill bit. They serve to remove chips and debris from the hole as the bit cuts into the material. They are also typically wider and deeper on larger diameter bits. Flute design can greatly affect the performance and efficiency of a drill bit.

When it comes to using drill bits, mistakes are not uncommon. These are some of the most common mistakes that you should avoid to ensure safety:

Black oxide is a coating made by blackening the surface of the drill bit to enhance rust resistance and reduce friction. It is made from iron oxide and magnetite. They are best used for drilling soft metals such as aluminum, copper, brass, and mild steel.

“This strike showed just how valuable our members are to the City of Brampton and the work they do to keep vital services running. Our members proudly stood up to defend and strengthen public services, and we can all hold our heads high knowing that we successfully fought for a fair agreement.”

One of the most important tools in any metalworker's arsenal is the drill bit. Drill bits are cylindrical cutting tools that are used to create holes in various materials such as metal, plastic, wood, ceramic tile, and concrete. But not all drill bits are made the same, and choosing the wrong one can lead to disastrous results.

Carbide (Carb) drill bits are made from tungsten carbide, which is a dense and durable material that can resist high temperatures and wear. They are ideal for drilling through hard materials, including ceramics, glass, and masonry, as well as hard metals like stainless steel and cast iron.

The drill point length refers to the distance from the tip of the drill bit to the beginning of the flute. There are three types of drill point lengths: standard, jobber, and long.

The agreement is tentative, pending ratification by CUPE local 831 members later this week Once ratified, members will begin the process of returning to work starting Saturday, November 16.

Using the wrong bit can result in damage to the material, decreased efficiency, and even injury to the user. Therefore, it's essential to understand the various types of drill bits available and their unique features, including materials, coatings, point angles, and lengths.
