Centre Drills

Buy Best Quality Centre Drills at Best Prices Online

Centre drills are available in different sizes and material quality, and are designed to make various holes in metal workpieces. These cutting tools are designed using premium-grade materials to offer exceptional durability to last longer while making holes through dense metal pieces. They don’t deform easily or corrode, which increases their lifespan, unlike the standard drill bits that only last a few sessions. There are various types of drill bits that are categorized based on their specific design and shape, along with centre thickness, to make high-precision centre holes in metal work pieces.

What are Centre Drills?

Centre Drills are small cutting tools that have high thickness in the centre and sharp end points at both sides. They are used for making pilot holes or starting holes in metal workpieces using the milling and CNC machines. These drill bits are made from premium grade steel to offer exceptional toughness to last longer than standard drill bits. Centre drills also create a high precision centre hole without going off of the target, in comparison to standard bits.

Major Types of Centre Drills Available

Type A Centre Drills

These are the most common types of centre drills used for making an initial center point or pilot hole into a work piece. They are used for initiating the reshaping of metal pieces by starting at the centre. These bits have a 60 degree conical countersink angle and straight cutting pilot.

Type B With Protective Chamfer

These drill bits have a 60 degree standard countersink along with a 120 degree protective chamfer on the outer edge for better efficiency. These bits are used for heavy duty applications to deal with large workpieces. The 120 degree chamfer protects the 60 degree cone from deforming during the machining process.

Type R (Radius)

Most standard centre drills have a straight chamfer angle. However, the type R bits have a curved radius to achieve a unique design that holds on much better when making a centre starting hole.

Unique Features of Centre Drill Bits

• Rigid Construction: Short, thick body provides high strength and stiffness.
• Accurate Centering: Produces precise center holes for machining operations.
• Pilot Point: Small drill point guides the tool accurately into the workpiece.
• Countersink Section: Creates a conical seat for lathe centers.
• Anti-Wandering Design: Minimizes drill deflection and improves alignment.

What are the Major Benefits of Using Centre Drills?

Higher Drilling Accuracy

One of the biggest benefits of centre drills is that they create an exact starting point for drilling. This helps prevent the drill bit from slipping or moving away from the marked position, leading to more accurate hole placement.

More Stability

Centre drills create a guide hole that helps larger drill bits stay in the correct position. This improves stability during drilling and helps produce more accurate and consistent results.

Less Wear on Drill Bits

Starting a hole directly with a standard drill bit can put extra pressure on the tool. A centre drill reduces this stress by creating a starter hole, which helps the main drill bit last longer and lowers tool replacement costs.

Improved Hole Quality

Because the drill starts in the correct position, the finished hole is usually cleaner and smoother. Centre drills help reduce vibration and uneven cutting, which improves the overall quality of the workpiece.

Higher Productivity

Centre drills help avoid mistakes such as misplaced holes and drill wandering. This reduces the need for rework and saves time, allowing machining tasks to be completed more quickly and efficiently.

Useful for Lathe Operations

Centre drills are often used to make center holes in workpieces that will be mounted on a lathe. These holes provide support and help keep the workpiece stable during turning operations, improving accuracy.

Suitable for Many Materials

Centre drills can be used on different materials, including steel, aluminum, brass, cast iron, and plastic. Their ability to work with various materials makes them useful in many machining and manufacturing applications.
