Dormer A002 Series HSS-TiN Twist Drill Bit for Steel, 7.2mm Diameter, 109 mm Overall

Introducing the A002 series of high-quality, industrial HSS-TiN Jobber Drill Bits from Dormer. The professional Drill Bits have been manufactured from premium-quality HSS steel featuring a Titanium Nitride coated tip for increased wear resistance, the service life of drill and better cutting performance when drilling harder materials. Drill Bits feature 118° point angle for precise application. Easy to read size markings are engraved on the side of each drill bit. Drill's helix has been redesigned for greater stiffness. Dormer A002 professional general-purpose drills are suitable for both hand and machine use and are ideal for drilling into steels, cast steel, grey cast iron, malleable cast iron, nickel-brass, aluminium alloy and graphite, plastic etc. (Not suitable for masonry applications).

• Features self-centring split-point for excellent positional accuracy and hole quality
• TiN tip coating for extended tool life & increased performance (2.0mm and above)
• Optimised Web Design for increased strength and rigidity
• Will drill up to 4xD in steel, stainless, cast iron, plastics and many other materials with ease
• Suitable for both hand and machine use
• 118° split point design for better centring and precise application
• Available in a range of diameters from 3 mm → 13 mm

Note: With diameters ranging from 3 → 6.9 mm, these drill bits are sold in 5-piece / 10-piece packs or individually from the 7 mm size.

• DIN338RN
• ISO235
• BS328

These bits are ideal for fast drilling of a plug, anchor or clearance holes in a number of materials such as steel, plastic, wood, metal etc. This makes it an essential piece of kit to have if you work within the carpentry/construction/engineering industries to save time and money on being able to perform more efficiently when working with stubborn materials.

Can these drill bits be used with any SDS drill?
No, they are standard drills, will not fit into SDS chuck

What does jobber mean?
The word jobber specifies the length of the drill bit. This generally means the length of the entire drill bit itself is significantly longer for diameter it has. As an example, a mechanic drill bit will have a much shorter flute and therefore have a much smaller overall length.

What is HSS?
An acronym for High-speed steel, HSS is generally the go-to type of steel needed for drill bits due to their excellent heat resistance at high speeds. As a standard drill can spin upwards of around 500 - 700rpm, the friction can cause a substantial build-up of heat. Something which would not be wanted when working with wood and plastic.

This high-speed steel TiN drill bit by Dormer is a precision tool designed for industrial use. With a diameter of 7.2mm and an overall length of 109mm, this long-length drill bit is ideal for metal drilling applications. It features a 7.2mm shank, making it suitable for heavy-duty tasks requiring precision.

• Twist drill bit design for efficient drilling
• HSS-TiN material for increased durability and heat resistance
• Overall length of 109mm for extended reach
• 7.2mm shank size for a secure fit in the chuck

• Ideal for metal drilling applications in the automation and mechanical industries
• Suitable for precision drilling tasks that require a high-quality finish
• Can be used for heavy-duty industrial projects that demand durability and accuracy
