HSS GROUND Pro LONG Series Drill Bit – M2

The HSS ground long series drill bit is the go-to choice when a standard jobber length just won’t reach. Made from M2 high speed steel and fully ground throughout, these bits cut cleanly through mild steel, aluminium, brass, and most general engineering materials without the rough finish you get from cheaper rolled alternatives. The extended flute length gives you the extra reach needed for deep-hole work, fabrication jobs, and situations where you’re drilling through thick sections or at an offset.

From 3mm upwards, every bit in this range features a 135 degree split point tip. That detail matters more than it sounds. A standard drill tip tends to skate across the surface until it finds somewhere to bite, which is why half the world reaches for a centre punch before drilling anything. The split point cuts on contact, so the bit locates itself immediately without wandering. No punch, no pilot hole, no frustration.

Where the HSS Ground Long Series Drill Bit Earns Its Keep

Long series bits are a staple in fabrication shops, engineering workshops, and on site wherever you’re working through box section, angle iron, or plate that a stubby bit can’t comfortably reach. They’re also useful when you need to drill at a slight angle and require more of the shank clear of the workpiece. Electricians occasionally reach for them when chasing out deeper channels or drilling through thick timber and board in one pass.

The M2 steel grade holds an edge well under heat. It won’t last forever on stainless or hardened materials, but for everyday steel, aluminium, and similar, it performs consistently without needing constant resharpening. Fully ground geometry means the cutting edges are accurate from the start, which shows up in hole quality and dimensional accuracy.

Available in a wide range of sizes from 2mm up to 10mm, with single bits or multipacks to suit both occasional use and heavy workshop demand. At this price point, keeping a few spares on the shelf makes sense.
