What do center drill reviews really tell you before you buy a set?
Worth it, with a caveat
Why a drill bit skates off round metal
You've felt a twist bit skate sideways the second it touches a rounded bar, walking off the mark before it's cut anything at all. That skid is what sends people digging through center drill reviews looking for a fix, because it eats blades and patience in equal measure. The fix isn't a sharper twist bit. It's a completely different shape, and the question is whether a small, cheap box of them can actually deliver it.
How a center drill actually finds true center
A center drill isn't a small twist drill with a fancy name. It's short, thick shanked and stiff on purpose, so it can't flex sideways the way a long twist bit does, and the tip carries two angles instead of one: a stubby point ground at sixty degrees that starts the hole dead center, backed by a wider body that cuts a countersunk cone in the same pass. That cone matters more than it looks. On a lathe, it's what a tailstock centre or a live centre actually sits in, so the accuracy of everything you turn afterward depends on that first small dimple being exactly where it should be. Feed it too fast or run it too slow and the tip is the first thing to give, which is why the steel matters more than the size stamped on the shank. This set is M2 high speed steel, which holds an edge under heat better than the low carbon steel some bargain sets use, but it's still a mid tier steel, not a premium cobalt blend, so it dulls faster on hardened stock than on mild steel or brass. Seven sizes from one to five millimetres cover what most home shops and small lathe projects actually need, stepping up gradually enough that you're rarely stuck between two. The case is plastic and it has one job, keeping seven small, brittle points from rattling against each other in a drawer, because a chipped tip on a center drill can't be resharpened back to true.
You're not buying seven drill bits, you're buying seven guaranteed starting points, each one landing exactly where you marked it. The steel decides how many of those starts you get before the tip gives up, not the size stamped on the box. Sixty degrees and a stiff, stubby shank do the actual work, everything else here is packaging.
Who this center drill set is for, and who should skip it
Worth it if
- you turn metal on a lathe regularly and need accurate starting holes
- you work mostly with mild steel, aluminum, or brass
- you want a range of small sizes without buying bits one at a time
Skip it if
- you mainly drill wood, drywall, or masonry
- you're cutting hardened steel all day and need premium cobalt tooling
- you need bits that survive rough handling in a shared shop
Skip it if you need bits that survive hardened steel all day or rough handling in a shared shop.
The center drill bits set verdict, is it worth it
If you turn metal on a lathe often enough that a wandering bit costs you real material, this set earns its spot in the drawer. If you're drilling wood or drywall, or you need something that shrugs off hardened steel all day, this isn't that tool, and a heavier cobalt set will outlast it.
That skidding, off-center start disappears the moment you swap to one of these: touch the tip to the stock, it bites, and the hole sits exactly where the mark was. On day one, that's the whole payoff, no redrilling a countersink you already ruined trying to eyeball it. A lot of buyers running these on ordinary steel and brass report exactly that, the accuracy is where the set consistently earns its keep, even as opinions split on how many sizes hold up under harder or repeated use.
Amazon shoppers rate it 4.5 out of 5 across 1,765 ratings. That is their number, not ours.
Before you go
What's the difference between a spot drill and a center drill?
A spot drill has a single cutting angle meant to mark a starting point for a twist bit, while a center drill cuts a small hole and a countersunk cone in one pass, sized to seat a lathe centre.
What is the ideal speed for using a center drill?
Center drills generally run best at higher spindle speeds and lighter feed than a same-size twist bit, since the small stiff tip is more likely to chip than bend if you push it too hard.
What is the most reliable drill brand?
Reliability comes down to the steel and grind more than the name on the shank, M2 high speed steel holds an edge on mild steel and brass, while cobalt blends last longer on hardened material regardless of brand.
