In This Article
Cutting stainless steel cleanly is one of those jobs that looks simple until you ruin a $40 bit in under a minute. Stainless work-hardens fast, punishes dull teeth, and exposes cheap hole saws almost immediately. Buyers often complain that what worked fine in mild steel suddenly smokes, chatters, or snaps teeth when stainless enters the picture. The comparison below focuses on carbide-tipped hole saws that are actually designed for stainless steel, pulling from expert testing, real-world YouTube cut tests, and long-term community feedback to separate tools that survive stainless from those that don't.

DDP Score Breakdown
DDP Score = 8.5/10 | Based on Amazon (866 ratings), Expert Reviews, Reddit Community, YouTube Reviews, Review Text NLP (13 analyzed) Key Findings
Pros
- Tungsten carbide teeth maintain sharpness through repeated stainless cuts, especially in 14–18 gauge electrical enclosures. (expert testing lab)
- Quick-Change arbor system reduces swap time to under 10 seconds during multi-hole panel work. (trade review site)
- Cuts clean holes with minimal burr formation when run below 350 RPM. (YouTube tech reviewer)
Cons
- Limited to smaller diameters, making it unsuitable for conduit or pipe penetrations over 1-1/4 inches. (Reddit community)
- Premium price compared to similarly sized EZARC cutters with comparable longevity. (user review analysis)
Product Overview
The Greenlee 645-1-1/8 Quick-Change Carbide-Tipped Hole Cutter has built a reputation on commercial jobsites where stainless steel is unavoidable. Trade-focused expert reviews and electrician forums frequently cite its ability to cut 14–18 gauge stainless without work-hardening the material. Reddit metalworking threads echo that sentiment, with users reporting dozens of clean holes before performance drops. While YouTube reviewers are more mixed on vibration, most agree the carbide teeth outperform bi-metal alternatives in stainless applications.
This cutter uses individually brazed tungsten carbide teeth rather than a continuous edge, improving heat resistance during slower RPM cuts. The 1-1/8-inch diameter targets knockout replacement work, and Greenlee recommends sub-350 RPM operation with cutting oil. Expert review sites emphasize that the Quick-Change arbor system saves time during panel fabrication. If arbor compatibility matters, our buying guide below explains why proprietary systems can be a deciding factor.
What Users SayWith 866 Amazon reviews averaging 4.7 stars, satisfaction is consistently high. Community feedback highlights reliability more than speed, especially among electricians and HVAC techs.Greenlee 645-1-1/8 Quick-Change Carbide-Tipped Hole Cutter : In-Depth Analysis
In real-world testing shared by YouTube electricians, the Greenlee 645 consistently cut stainless panels in under 30 seconds without blueing the metal. Reddit users stress that backing off pressure near breakthrough prevents tooth chipping. Several forum members reported over 25 holes in 16-gauge stainless before noticeable dulling. However, aggressive drilling on handheld drills increased chatter compared to heavier drill presses.
At $35.39, the Greenlee costs more than EZARC's similarly sized cutters but less than stepping up to Klein's larger carbide options. Reddit discussions generally frame it as a reliability purchase rather than a bargain. If you're deciding whether quick-change arbors justify the price, our buying guide breaks down when proprietary systems actually save money long term.

Final Verdict
The Greenlee 645 remains a favorite among professionals because it prioritizes consistency over gimmicks. In side-by-side stainless tests shared by YouTube reviewers, it cut faster and cleaner than bi-metal competitors, though slightly slower than larger Klein carbide cutters. Compared to the EZARC 1-1/8-inch model, Greenlee's edge life is longer, but the price premium is real. If you already use Greenlee arbors and value fast swaps, it earns its Editor's Choice badge.

Pros
- Large carbide teeth withstand heat buildup during extended stainless cuts. (N/A)
- Clean hole edges reduce secondary deburring work. (YouTube tech reviewer)
- Compatible with standard arbors, avoiding proprietary lock-in. (forum feedback)
Cons
- High torque demand makes it unsuitable for lightweight drills. (Reddit community)

Product Overview
The Klein Tools 31870 targets larger stainless cutouts that smaller hole saws can't handle. Expert review sites praise its carbide teeth longevity, while Reddit users emphasize proper tool control. YouTube reviewers show it cutting stainless sinks successfully, albeit slowly. It's clearly built for tradespeople, not casual DIYers.
At 2-1/2 inches, this cutter dramatically increases torque requirements. Klein uses thick carbide tips designed to resist chipping under heat. Expert testing notes reduced tooth wear when RPM stays under 250. Buyers unsure about drill compatibility should review our buying guide below.
What Users SayWith 566 reviews averaging 4.6 stars, feedback is strong but polarized around torque demands.Klein Tools 31870 Heavy Duty Hole Cutter : In-Depth Analysis
YouTube cut tests show clean stainless penetration in about 60–90 seconds depending on thickness. Reddit users recommend pausing mid-cut to cool the bit. Several reported over 15 sink cutouts without tooth failure. Handheld use without a side handle often led to wrist strain.
Priced at $51.99, it's significantly more expensive than EZARC single cutters. However, forum users argue replacement costs are lower long term. If you're weighing size versus control, our buying guide explains how diameter impacts drill selection.

Final Verdict
The Klein 31870 trades finesse for muscle. Compared to the Greenlee 645, it removes far more material per cut, making drill stability critical. YouTube testers consistently recommend drill presses or side-handle drills. While expensive, its durability in thick stainless earns its Runner-Up spot for users who can control it.
