Standard Metric Double-Ended HSS-G Series Drill Bit ideal for use with wood, plastics & thin gauge ferrous metals. The Short length is ideal for operation in tight spaces & the Double-ended design enables easy & rapid bit changes.

Features & Benefits
Black oxide coating offers self-lubricating properties, maximum chip extraction, increased heat resistance & increased corrosion resistance
135° split point tip geometry prevents bit walking for fast & accurate material penetration
Double-ended design enables easy & rapid bit changes
Short length ideal for operation in tight spaces
Ground forged edge & flute construction for high quality performance & long life

HSS-Co cobalt double-ended drill bits are designed for drilling thin metal materials, bodywork panels, holes for riveting, stainless steel and stronger materials. Cobalt-alloyed steel with 5% cobalt content helps in more demanding work and both working ends increase the practical usability of the drill bit.

Types of Drill Bit
There are many different types of drill bits available which we’ll look at in this section. In the drill bit guide below, we’ve split them into three categories: type of drilling application or material being drilled, the best types of drill bits, and then shank types.

Drill bit material guide: Drilling applications

The most important factor to consider when buying a drill bit is the type of material you’re drilling into. This will determine the type of metal and coating the drill bit is made from and the shape of the cutting lip. Gold Surface Treated Fractional Two Ended Drill Bit

Here’s a list of the best types of drill bit to use for the most popular drilling applications or material types:

Image of Masonry Drill Bits
What drill bit for masonry?

A specialist masonry drill bit is the best type of drill bit to use if you’re drilling into brick, block, concrete, natural or artificial stone. They prevent the likelihood of chips and cracking and can help to reduce noise levels. They’re typically made from high-speed steel with a tungsten carbide cutting lip. They can have two, three or four cutting lips – the more cutting lips there are, the harder the material it will cut into. Most masonry drill bits can be used with a hammer action drill, but check before buying. 1/8in Double Ended Drill Bit Set
