Drill Bits

Tungsten carbide (TCT) cutting edge allows drilling into concrete, aerated concrete, bricks, slate and granite.

From Ø 5 mm the drill bits have a three-flat shank to prevent slipping in the chuck.

For Ø 3 & 4 mm the drill bits have a round shank.

The red flute makes identification easier for the user.

They can be used with rotary hammers, using the keyless chuck and selecting rotation mode.

MILWAUKEE® HSS-G Co drill bits combine high-speed steel and cobalt for superior precision, longer life and heat resistance. These high-performance drill bits are designed for fabrication, production and machining applications on hard metals and in conditions of heavy heat generation. Add a premium drill bit with precision sharpening to your kit with MILWAUKEE®. Choose from HSS-G Co drill bits in different diameters and lengths to suit your needs. The addition of cobalt makes these drill bits even harder and more heat-resistant than standard HSS drill bits. For greater versatility, MILWAUKEE® offers multi-size sets complete with sturdy cases to organise and carry your tools conveniently. Each HSS-G Co drill bit is made from high-speed steel alloyed with 5% cobalt and complies with DIN 338, ensuring quality and reliability for your investment. Use them to drill high-alloy steels and metals with a tensile strength above 1000 N/mm², smoothly and efficiently. The special QUAD EDGE™ point allows quick, precise starting, with a split 135° angle that eliminates slipping. The variable flute geometry ejects material more quickly, reducing the risk of tool overheating. The reinforced core, wider towards the shank, provides extra strength and less need for replacement

The Thunderweb geometry allows faster chip ejection. It also dissipates heat better. These two features give greater drilling speed and longer drill bit life.

The parabolic section reduces the risk of the drill bit jamming in deep holes

The web is thicker and increases towards the shank (tapered web). The parabolic section offers greater strength, lower risk of breakage, excellent for particularly deep holes, longer life

Cutting angle: 135°.

Bright finish allows faster chip removal and longer drill bit life.

ABS case with rubber corners for greater durability.

Withstands high pressure loads.

Designed for use with the impact driver and

drills / drivers.

Hex shank up to 260mm length, three-flat shank up to

400mm length.

Tungsten carbide (TCT) cutting edge allows drilling into

concrete, bricks, roof tiles, concrete blocks, thin metal,

medium-soft ceramic tiles, all types of wood

and PVC.

White flute for easy identification.
