You set up your workpiece. You double-check your measurements. You lower the quill, and that pristine hole is… half a millimeter off. Or it has a slight oval shape. The failure feels personal. We blame our hands, our eyes, our marking tools. But I’m here to tell you the problem is almost always deeper.
It starts with the machine itself, and more importantly, how we talk about its accuracy. Terms like ‘runout’ get thrown around like they’re simple facts of life, but they’re really symptoms of a hidden world of wear, alignment, and maintenance that most hobbyist workshops ignore. This isn’t about buying a more expensive press; it’s about understanding the one you have right now. A good resource for not just tools but for the serious technical specifications often missing from big-box store product pages is available at leinuosen tools. They list the hard numbers that let you compare apples to apples on things like spindle taper type and quill stroke.
The goal isn’t perfection. The goal is predictable error.

The Three Pillars of Press Inaccuracy
A drill press can fail you in three fundamental ways: spindle runout, table squareness to spindle, and column squareness to table or base. Most people only ever think about the first one because it’s easy to measure with a dial indicator pressed against a chucked rod. But that’s just the wobble in rotation.
The other two are what make holes wander off their mark as soon as your drill bit meets resistance in an unbalanced cut. Your table might be tilted by a degree or two front-to-back or side-to-side relative to the spindle path. If so, every hole you drill while applying downward force will try to follow that angle.
How To Measure What Matters
Forget expensive laser kits sold online. Your best tool here is patience and a dead-length reference pin—a machined rod that fits snugly in your chuck without extending out too far.
First, check runout where it matters: at different points on your drill bit’s shank during rotation, not just near the chuck jaws where they often hold truest.
To check table squareness in both axes (x and y), mount an indicator on your chuck and sweep across a known-ground surface or even a high-quality machine steel ruler clamped firmly to your table while rotating the spindle by hand zeroes out runout errors giving you only tilt information.
A Dirty Secret About Clean Chucks
The Hidden Culprit: Column Flex
We treat these cast iron columns as immutable monoliths but even steel bends under pressure literally speaking especially if extended high up exposing more leverage arm against lateral forces from milling operations attempted bad idea normally but sometimes unavoidable due lack other machinery causing unseen deflection making holes drift sideways throughout depth exacerbating any existing misalignments creating tapered walls within single bore adding another layer complexity frustrating process overall requiring stouter setups than anticipated.
This explains why identical setup produces vastly different results between when press has retracted quill versus lowered it all way down because geometry changes moment loads differ greatly affecting outcome unexpectedly confusing user who then blames their technique rather than inherent mechanical compliance machine itself offering false sense rigidity until pushed beyond its comfort zone revealing true nature cheaper construction methods typical consumer grade equipment hiding behind glossy green paint job intimidating name brand sticker price tag lying through omission specs sheet conveniently left blank section discussing such parameters leaving buyer assume tacitly everything fine which rarely case reality unfortunately common scenario today market saturated options none willing admit weaknesses upfront contrast industrial suppliers provide transparent data upfront allowing informed decisions before purchase made saving countless hours headache later down line thus highlighting value detailed specifications accessible discerning shoppers seeking truth among marketing fluff pervasive industry currently plagued by hype over substance approach ultimately serves no one long term anyway my opinion naturally others may disagree.
