The angle ground into the tip of a drill bit has a big effect on how it starts, how it cuts, and which materials it suits. Here’s what drill bit point angles mean and how to choose between the common 118° and 135° points.

What Is a Drill Bit Point Angle?

The point angle is the total angle formed at the very tip of the bit, where the two cutting edges meet. A smaller angle makes a sharper, more aggressive point; a larger angle makes a flatter, tougher point that resists walking. It directly affects how easily the bit bites in and how well it handles hard materials.

118° — The General-Purpose Point

A 118° point is the classic, all-round angle. Its sharper tip penetrates easily, making it a great choice for wood, plastic, aluminium and softer steels. The trade-off is that it tends to “walk” on hard, smooth surfaces unless you centre-punch first.

135° — The Split Point for Hard Metals

A 135° point is flatter and almost always a split point, which self-centres and starts drilling on contact without wandering — no centre punch needed. The flatter angle spreads the cutting load, so it stands up far better to hardened and stainless steel. This is the point you want for tough metal work.

Which Should You Choose?

For general drilling in wood and soft metal, a 118° bit is perfect. For stainless, hardened or abrasive metals — or any time you want the bit to start exactly on the mark without a punch — choose a 135° split point. Matching the point to the material means faster, cleaner holes and longer bit life. Learn more in our drill bit materials guide.
