Description
Positive Features of the Greenlee 660 Quick Change Carbide Cutter Set
Put this hole cutter set through its paces and the precision and speed it offers truly stand out. The quick change arbor is a game-changer; it allows cutter heads to be swapped with just a push and turn, eliminating wasted time fumbling with tools. The kit covers a versatile range of hole sizes, from 7/8-inch up to 2 inches, making it incredibly flexible for various tasks involving stainless steel, mild steel, copper, and aluminum. The precision carbide teeth not only slice through metals cleanly but also reduce the usual chatter and squealing that can drive you nuts during drilling.
The flange stop is a thoughtful addition, preventing over-drilling and protecting the workpiece. Plus, the replaceable cobalt-steel pilot drill with its split-point tip keeps the tool from wandering off target, which is a must for accuracy. All the components come neatly packed in a rugged plastic case, which helps keep things organized and portable. The kit is positioned as professional-grade equipment, and the finish on the arbor and heads matches that billing.
- Cuts clean, precise holes in multiple types of metal
- Quick change arbor speeds up the workflow
- Durable carbide teeth minimize noise and wear
- Flange stop prevents over-drilling for better control
Areas for Improvement
While there is a lot to appreciate about this cutter set, a few drawbacks surface. The weight of the kit, sitting around 1.3 pounds, can add up when you’re working overhead or for extended periods. Also, the plastic carrying case, though rugged, is a bit bulky for a packed toolbox and could stand to be more compact. Another minor gripe relates to the minimum chuck size requirement of 3/8 inches on the arbor. If you’re using a drill with a smaller chuck, this kit won’t fit without an adapter.
Additionally, although the carbide teeth are tough, they demand careful handling to avoid chipping. The price point might feel steep for casual DIYers, although professionals will likely find the investment justified by the tool’s longevity and performance.
- Slightly heavy for prolonged overhead work
- Bulky plastic case takes up toolbox space
- Requires 3/8-inch minimum chuck size on drills
- Carbide teeth are durable but can chip if mishandled
Ease of Use and Design Considerations
The design of this hole cutter set caters well to professionals who value efficiency. The quick change arbor mechanism is intuitive; cutter heads swap over without breaking focus on the task. The flange stop is especially useful, capping drilling depth so the bit does not go too deep, which heads off a number of problems. The pilot drill’s split-point tip ensures the bit starts exactly where it is placed, limiting any walking or slipping on the metal surface.
The controls are simple enough that someone just starting out in electrical work can pick the set up and feel confident with it right away. The ergonomic design of the arbor and cutter heads makes gripping and guiding the tool comfortable, even when tackling tougher metals. The overall build quality is solid and reliable, helping to boost confidence during use.
Performance Across Different Metals
The cutter is rated for a variety of metals. It is specified for stainless steel, mild steel, copper, and aluminum. The precision carbide cutting edges are shaped to slice through each metal without producing excessive burrs. The design targets a significant reduction in the typical noises associated with hole cutting; it clearly aims to minimize chatter and squealing, which is a blessing for long jobs.
While the smaller cutter heads suit lighter metals like copper and aluminum, the larger sizes are built to hold their edge in tougher materials such as stainless steel. This versatility makes the set a solid pick for electricians, metalworkers, and maintenance professionals who need reliable results across different projects.
Product Comparisons
Compared to popular competitors like the Milwaukee hole saw kits or DeWalt’s carbide hole cutters, this set offers notable strengths in its quick change system and carbide tooth durability. The arbor’s push-button change is smoother and faster than the twist-lock systems used elsewhere. However, some rival kits offer slightly lighter cases or include more cutter sizes, which could be a consideration if you need a broader range.
Milwaukee’s sets sometimes come with more aggressive teeth for faster cutting but at the expense of increased noise and chatter. DeWalt tools tend to be pricier but include more extensive warranty options. The Greenlee cutter set strikes a good balance, especially for those focused on precision and professional-grade performance without overspending.
Value Proposition
The price for this hole cutter kit is in line with the quality and features it delivers. Although it’s not the cheapest option, the long-lasting carbide teeth and versatile cutter sizes make it a worthwhile investment for professionals who need reliability and speed. If you’re a casual user, the cost might seem high, but for electricians, plumbers, or metal fabricators, the time saved and accuracy gained justify the spend.
The rugged plastic case and included accessories, like the hex key and quick change auger, add value without inflating the price unnecessarily. Considering the tool’s durability and precision, it definitely offers money’s worth in the realm of hole cutters.
Alternative Offerings
Looking beyond this set, other options include the Milwaukee Hole Dozer and DeWalt’s Carbide Hole Saw sets. Milwaukee’s kit tends to deliver aggressive cutting and is often preferred when speed is prioritized over finesse. DeWalt’s offerings are known for their robust warranty and brand reputation but come at a higher price point. The Greenlee kit shines where precision and ease of head changes matter, especially in professional environments where downtime is costly.
If you need a lighter set with more size options, some brands include additional cutters, but they may lack the quick-change arbor feature, which speeds up work dramatically. For those who value a well-rounded toolset with professional-grade materials and efficient design, this hole cutter kit is a standout choice.
