The Grizzly Radial Drill Press: When a Fixed Column Is Not Enough

There is a moment every woodworker hits at the drill press: the hole needs to go somewhere the fixed column will not let the spindle reach, or into the middle of a panel too wide to swing under the head. On a standard press you are stuck. On a radial drill press, the head slides out along a horizontal arm and even tilts, so the spindle goes to the work instead of forcing the work to the spindle. Grizzly is one of the few makers offering that trick at a size and value that a home shop can actually justify, and for the right person it solves a real problem.

What a radial drill press does

On a radial press, the motor-and-spindle head rides on a beam that extends and retracts, dramatically increasing how far the bit can reach from the column. Grizzly’s radial models push effective reach far beyond what their column size suggests, which is the entire point. The head also tilts left and right, letting you drill angled holes without tilting the table and losing your workpiece off a sloped surface. That combination, extended reach plus a tilting head, is what separates a radial press from an ordinary one.

The tradeoff is rigidity. Any machine that puts the spindle on the end of an extending arm gives up some stiffness compared to a fixed column of the same size. Radial presses are best understood as reach-and-versatility tools, not maximum-muscle boring machines.

The Grizzly radial models

Grizzly’s radial drill presses (the G7945 and its relatives) are typically benchtop or short-column machines running a fractional-horsepower motor with a multi-step belt drive, an MT2 spindle, and a 5/8-inch chuck. The headline number is reach: the sliding head gives a swing far larger than a comparable fixed press. The heads tilt for angled drilling, and the tables tilt and rotate as well. Because Grizzly publishes full manuals, spec sheets, and exploded parts diagrams for these machines, you can confirm the exact reach, speed range, and travel for the specific model before buying, which is exactly what you should do given how much radial specs vary between models.

Who should buy one, and who should not

Here is the honest split. A radial drill press is the right tool if you regularly drill into wide panels, need to reach holes far from an edge, or want to drill angled holes with the workpiece sitting flat and secure. Furniture makers, boatbuilders, and anyone working large or awkward stock get real, repeated value from that reach and head tilt.

It is the wrong tool if your work is small and centered, or if you mainly drill metal and want maximum rigidity and power. In that case a fixed-column press of the same size will be stiffer and simpler, and you should buy that instead. Do not pay for reach you will never use.

Setup, tooling, and parts

A radial press benefits from the same core accessories as any drill press, plus attention to work-holding since your reach is longer. A solid drill press vise and a good clamp set keep large workpieces put. A quality 5/8-inch keyed drill chuck with an MT2 arbor sharpens accuracy at the end of that extended arm, and a set of Forstner bits makes the most of the reach for furniture work. Keep a spare drill press V-belt on hand, and use Grizzly’s model-specific parts diagram for anything beyond consumables.

The verdict

The Grizzly radial drill press is worth buying when reach and angle versatility are the problem you keep running into, and it is one of the few realistic ways to get a sliding, tilting head in a home shop. It shines on wide panels, edge-distant holes, and angled drilling with the work sitting flat. Respect its one real tradeoff, an extending arm is never as rigid as a fixed column, so it favors versatility over raw boring power, and match it honestly to your work. If you mostly drill small, centered holes, save the complexity and buy a fixed-column press. If you keep fighting the limits of a fixed column, the Grizzly radial is the machine that finally lets the spindle come to you.

Takeaways:

• A radial drill press has a head that slides along an arm and tilts, so the spindle reaches the work.
• Grizzly’s radial models (G7945 and relatives) offer far more reach than their column size suggests, plus a tilting head.
• The tradeoff is rigidity: an extending arm is less stiff than a fixed column of the same size.
• Buy it for wide panels and angled holes; buy a fixed-column press for small, centered, high-rigidity work.

FAQ

What is a radial drill press? A drill press whose head slides out along a horizontal arm and tilts, greatly increasing reach from the column and allowing angled holes with the workpiece flat.

What is the advantage of a Grizzly radial drill press? Much greater reach than a fixed press of the same size, plus a head that tilts left and right for angled drilling, which is ideal for wide panels and awkward stock.

What is the downside of a radial press? Rigidity. Putting the spindle on an extending arm gives up stiffness compared to a fixed column, so it favors versatility over maximum boring power.

What chuck and taper does it use? Grizzly’s radial models typically use an MT2 spindle taper with a 5/8-inch chuck. Confirm the exact spec in the model’s manual before buying an arbor.

Who should buy a radial drill press? Anyone who regularly drills wide panels, needs to reach holes far from an edge, or wants angled holes with the work sitting flat, such as furniture makers and boatbuilders.

Radial or fixed-column drill press? Choose radial for reach and angle versatility; choose fixed-column for small centered holes, maximum rigidity, and simpler metal drilling.

Where do I get parts for a Grizzly radial press? Grizzly publishes manuals, spec sheets, and exploded parts diagrams online by model number, and everyday consumables (belt, chuck, key) are generic.
