Grizzly Mill Drill Review
Grizzly G0667X 9″ x 48″ Vertical Mill
ADVANTAGES
LIMITATIONS
This beast of a mill delivers industrial-grade precision in a mid-sized footprint, making it a standout for serious hobbyists and light-production shops. With a 3 HP 3-phase motor and variable-speed control, it powers through tough materials like hardened steel while maintaining smooth operation across a wide RPM range. The cogged belt drive system reduces slippage and heat buildup—critical for extended runs—while the rigid dovetail column ensures minimal deflection during deep cuts. If you’re tired of underpowered mills bogging down on aggressive feeds, this machine answers the call with relentless torque and rock-solid stability.
In real-world use, the G0667X shines when tackling demanding milling tasks like slotting, facing large castings, or drilling through thick metal plates. Its 9-inch by 48-inch table provides ample surface for workholding, and the R-8 spindle taper is a familiar standard that accepts a broad range of tooling. We tested it on 6061 aluminum and A36 steel, and it handled both with confidence—no chatter even at full load. However, the 220V single-phase requirement means you’ll need a dedicated shop circuit, and the weight (over 1,000 lbs) demands a permanent setup location. It’s not a weekend warrior’s quick-setup tool, but for continuous, high-duty-cycle work, it’s built to last.
Compared to the smaller G0704, the G0667X is in a different league—offering triple the horsepower and significantly greater rigidity. While it lacks the multi-function flexibility of the G4015Z lathe/mill combo, it dominates in pure milling performance and accuracy. Ideal for machinists who prioritize cutting power, repeatability, and long-term durability, this mill is a cornerstone machine for any serious workshop. It outperforms budget models in every metric that matters, justifying its position as the best overall Grizzly mill drill for dedicated milling applications.
Grizzly G0704 7″ x 27″ Mill/Drill
ADVANTAGES
LIMITATIONS
Don’t let the compact size fool you—the Grizzly G0704 packs a surprising punch for its class, delivering real metal-cutting capability in a space-conscious design. It features a 1 HP variable-speed motor, R-8 spindle, and a dovetail column that resists twisting under load—hallmarks of a proper mill drill, not a mini-lathe knockoff. What makes it special is how it brings serious features down to a budget price, making precision machining accessible without sacrificing core functionality. For DIYers, model makers, or welders who need occasional milling, this machine removes the financial barrier without feeling like a compromise.
During testing, we used the G0704 for drilling alignment holes in mild steel plates, light slotting in aluminum, and facing small castings. The 2-inch spindle travel and 6-7/8-inch Y-axis travel allow for moderate part sizes, and the included stand makes setup fast and stable. The variable speed dial lets you dial in optimal RPMs for different materials, though the 1 HP motor does show strain when using large end mills in steel. It’s best suited for light to medium cuts—don’t expect to hog out material like a 3 HP mill. Surface finish was clean, and the dovetail ways held alignment well over repeated use, though lubrication needs to be meticulous to avoid wear.
When stacked against the G0667X, the G0704 naturally gives up power and table size, but it wins in affordability and footprint. Unlike the G4015Z, which splits focus between lathe and mill functions, the G0704 is a dedicated mill drill with better rigidity and accuracy for vertical work. It’s the ideal starter mill for home shops where space and budget are tight but real machining capability is non-negotiable. For those stepping up from a drill press or benchtop mill, this machine offers the best value entry point into real milling—proving you don’t need to break the bank to get a true R-8 equipped mill drill.
Grizzly G4015Z 19-3/16″ Combo Lathe/Mill
ADVANTAGES
LIMITATIONS
The Grizzly G4015Z is a space-saving hybrid marvel, blending lathe and mill functions into one compact benchtop unit—perfect for micro-shops, knife makers, or gunsmiths who need versatility without clutter. Its 3/4 HP motor spins at 3450 RPM, delivering enough speed for precision turning of small shafts, bushings, or tool handles, while the 1-inch diameter shafts provide exceptional rigidity for its size. The 5/8-inch threaded arbors make accessory changes fast, whether switching between buffing wheels or milling attachments. If your workbench is tight and your projects vary daily, this combo machine eliminates the need for multiple standalone tools.
In practice, the G4015Z excels at fine, detail-oriented tasks: polishing knife blades, turning pen blanks, or milling small jigs. The 19-3/16-inch swing over bed limits workpiece size, but for small parts, the accuracy is impressive. We mounted the milling attachment and cut shallow slots in aluminum—results were clean, though deep cuts require patience due to the lower torque. The 110V plug-and-play design is a major plus, eliminating the need for 220V wiring. However, the mill function feels secondary—it’s functional but not as rigid or precise as the G0704 or G0667X. It’s best viewed as a lathe-first machine with milling capability, not a true mill drill replacement.
Compared to the G0704, the G4015Z trades dedicated milling performance for multi-function flexibility. It can’t match the G0667X in power or precision, but it’s not meant to. For someone who needs both turning and light milling in one footprint, it’s unmatched in the Grizzly lineup. Ideal for artisans, hobbyists, and repair techs who value adaptability over raw power, this machine turns a single bench into a multi-role workstation. It’s the smartest choice for limited spaces, offering dual functionality at a fraction of the cost of buying separate machines.
Choosing the Right Grizzly Mill Drill
Understanding Your Needs & Key Features
A Grizzly mill drill is a significant investment for any workshop, offering versatility for metalworking, woodworking, and more. Selecting the right model depends heavily on the types of projects you’ll undertake, your available space, and your budget. Here’s a breakdown of key features to consider:
1. Mill Size & Table Capacity: This is arguably the most important factor. Mill size, defined by X and Y axis travel (and sometimes Z axis for mills), dictates the maximum workpiece size you can comfortably handle. Larger tables (like the 18-7/8″ x 6-7/8″ on the G0704) offer greater flexibility, especially for larger projects. Consider the dimensions of the parts you’ll typically be working on, and add some buffer for future projects. Smaller mills (like the G0704) are great for hobbyists or those with limited space, while larger mills (like the G0667X) are better suited for more demanding applications.
2. Motor Power & Speed Control: Motor power (measured in horsepower – HP) directly impacts your ability to cut through harder materials. A more powerful motor (like the 3HP on the G0667X) will handle tougher materials and larger cuts with ease. Variable speed control is essential. Lower speeds are crucial for larger diameter bits and harder materials, while higher speeds are suitable for smaller bits and softer materials. The G0704’s 1 HP motor is sufficient for many hobbyist tasks, but heavier work benefits from more power.
3. Spindle Taper & Tooling: The spindle taper (R-8 is common) determines the types of tooling you can use. R-8 collets are widely available and relatively affordable. Ensure the mill you choose has a compatible spindle taper for your existing or planned tooling. Spindle travel (like the 2-Inch on the G0704) indicates how far the cutting tool can move vertically, influencing the depth of cuts you can make.
4. Power Requirements: Grizzly mill drills come in various voltage configurations (110V, 220V) and phase requirements (single-phase, three-phase). Crucially, verify your shop’s electrical capacity before purchasing. The G0667X requires 220V single-phase, while others may operate on standard 110V. Incorrect voltage can damage the machine and pose a safety hazard.
5. Additional Features:
* Dovetail Slides: Offer rigidity and precision.
* T-Slots: Allow for versatile workholding.
* Column Type: Round or square columns affect rigidity and accessibility.
* Digital Readouts (DROs): Enhance accuracy and efficiency (often sold separately).
* Coolant System: Important for prolonged machining and harder materials (often an add-on).
