Side holes

Are you worried about corrosion on your workpiece by insects or slugs? Then you should have side holes in your drill bits which will enable you to easily pull out the slugs damaging your workpiece.

Very often we face casualties such as damaged glass due to drilling, and this is due to the slugs that inhibit your workpiece longevity. But side holes pull in those slugs in their holes while drilling

And comes out preserving them and then you can easily remove those with bare hands. This way you don’t have to worry about corrosion while drilling and you will be served a neat and clean hole.

Nickel Plating  

An unparalleled characteristic in a drill bit is nickel plating. This helps with your anxiety about corrosion on your workpiece. Nickel plating serves the utmost resistance against abrasion. If you want your drill bit not to underperform, then it’s a must.

Because nickel plating provides you tight tolerance work which is actually the minimum deviation from specified components and features. It helps in reducing friction and it’s a uniform plating with no edge build-up.  

Carbide

Carbide is a fundamental component of a drill bit. It is a binary chemical compound of carbon especially used in metals with lower electro-negativity. Also, carbide is among the hard substance in comparison to others. It is denser than steel and provides you a butterlike surface finish.

Carbide provides the utmost efficiency in your work by retaining the cutting edge. Carbide helps you maintain hardness in your drill bit even in high temperatures which generate high drilling speed. This way you get a smooth and neat hole in your workpiece.

Carbide also enhances your drill bit longevity. Also, carbide resists abrasion. Carbide provides you a sharper edge to drill through pretty easily. 

Relief holes

When do you get the desired outcome in cases of drilling? How would you like it if your drill bit serves you a smooth and butterlike hole through drilling right from the very base of your workpiece in order to avoid rough outcome!! Yes, relief holes serve you that purpose.

Relief holes basically drill by weakening the glass structure at first so that your workpiece is dealt with less friction. This way it takes off the pressure from your hand and lets you drill at ease.

Flat shank

You might be wondering, why a flat shank? First, let’s take you to the concept of a shank. A shank is basically another word for the handle. When you are using any kind of tool, a handle to connect you with the operating end gives you the upper hand in your work.

A shank is the end part of your drill which acts directly with your workpiece. Now a flat shank reduces slippage while drilling, allowing higher torque and greater centering accuracy. Thus it helps you to adapt to any kind of workpiece through smooth rotation and also with little pressure from the upper body of your drill bit, thus your hand.

Diamond Edge

Are you looking for something small but sharp and robust? Glass is among the delicate materials as a workpiece and very ductile to deal with. So you are gonna need something small and sharp. A diamond edge will just serve you just right. Diamond is known to be the hardest substance in the world.

It is considered as a prime candidate in drill bits for its sharpness and larger drilling surface. Diamond edges help you cut through glass with the larger cutting surface. Drill bits with diamond edges have higher drilling efficiency and prolonged lifespan.

Diamonds will embed into saw edges and drill ridges through a metal bonding process that utilizes heat to seal the crystals into the edge of the tool. It protects your drilling end from abrasion. It can withstand heat and produces less debris on your workpiece.

It provides you a neat and clean drill with higher accuracy and emitting less heat while drilling.

Conclusion
