If you are a skilled tradesperson or an experienced DIY enthusiast, chances are your drill is one of the most frequently used tools in your possession. That is why, at Tiger Supplies, we provide you with an extensive range of  Drill Bits & Drill Accessories.

A drill bit is a cutting tool that is inserted into a power drill and used for creating holes in materials. While they come in different shapes and sizes, they all consist of similar components:

Point: The conical top part of the drill bit, including a spur and cutting lip.

Spur: Located at the top centre of the point. It helps position the drill bit accurately.

Cutting lip: The portion responsible for cutting through the material.

Flutes: These are the spiral channels that extend from the cutting lip to the shank. They aid in the removal of material during drilling.

Shank: The part of the bit that fits into the drill's chuck. 

The main distinguishing feature is typically the cutting lip design, which makes some more suitable for cutting through specific materials than others. Furthermore, there are variations in design based on the power drill and the type of hole to be drilled.

Before purchasing any set, it is crucial to consider your specific needs. While multipurpose drill bits are available, using a drill bit specifically designed for the material and type of hole being drilled will yield superior results.

The suitability for drilling into particular materials often depends on the composition and coating. The following descriptions outline the main options:


  1. High-speed steel is suitable for drilling wood, plastic, and soft metals.
  2. Cobalt is the best drill for stainless steel as it is a strong alloy metal that withstands heat and resistance.
  3. Carbide-tipped is among the hardest materials globally. It features carbide only at the tip. It is suitable for drilling masonry, tiles, and concrete.
  4. Solid carbide is entirely made of carbide. It is suitable for drilling into tough materials.
  5. Tungsten carbide is composed of tungsten metal and carbon. It is even more durable than standard carbide. This material is suitable for drilling extremely tough materials like masonry.

Drill bit coatings:

  • Black oxide: The advantage of this coating is that it helps retain lubrication. Thus, it is ideal for preventing rust formation.
  • TiN: This coating reduces wear and tear on bits designed for cutting metal.

TiAIM: It enhances resistance to abrasion and heat for drill bits that cut metal.

SG: This drill bit coating facilitates penetration of dense metals.

At Tiger Supplies, we also offer purpose drill bits, such as HSS Drill Bits sets  and SDS Drill Bits sets:

  • HSS (High Speed Steel) : It is multipurpose and can be employed on wood, metal and plastic. HSS drill bits are particularly well-suited for soft metals.
  • SDS (Slotted Drive Shaft) : It provides extra security and facilitates exceptional hammer action. SDS drill bits make drilling holes in concrete, block, and stone much easier.
