Best Deburring Tool for Machinists and How Noga and Shaviv Compare

For most machinists, the best deburring tool is a Noga NG1 handle with S10 blades. If you need reach on long straight edges and hole edges, the Shaviv E-handle set with E100 blades is the better tool. If your burrs live mostly on drilled holes, add a countersink-style deburrer, because a swivel blade is the wrong shape for that job. These picks weigh what the published record actually contains: Practical Machinist's community consensus, ToolGuyd's breakdown of the Noga line, the makers' own specs, and a decade of forum threads in which machinists argue about handles. Nobody in that record ran a controlled blade-life test, and that gap matters later.

Noga wins the default slot on popularity, price and a blade change nobody complains about. Practical Machinist's deburring roundup calls Noga the most-mentioned hand deburring brand among its members. It builds the recommendation around the ergonomic NG-1 handle and three interchangeable blades, the S-10, S-20 and S-35, which the article says cover coarse through super-fine work.

The S10 is the blade that ships in most drawers. ToolGuyd identifies it as Noga's standard general-purpose "heavy duty" blade. A separate roundup at Electrician Apprentice HQ lists it for plastic, steel and aluminum. On Noga's own site, heavy duty means a 3.2 mm swivel blade and light duty means 2.6 mm. The swivel is the whole point of the design. The blade follows the edge contour, so you do not rotate your wrist around a bore.

One caution about the S20 and S35. The Practical Machinist article ranks them from coarse to fine and says no more. Forum advice sometimes assigns the S20 to stainless and brass, but none of the sources here publish that assignment. Treat it as shop lore until Noga's blade chart says so.

Price. At the time of ToolGuyd's write-up, basic Noga sets ran under $15, and some McMaster-Carr listings were under $12 before shipping. ToolGuyd also lists Zoro, MSC and Amazon as sources, so replacement S10s are about as easy to find as anything in the industrial catalog.

What reviewers liked. Electrician Apprentice HQ calls blade changes "very easy" and credits the positive lock mechanism. It also likes that spare blades store in the handle.

The drawback. The numbering. Noga's S-series does not map by name onto anyone else's, and the "NOGA Deburring tools, what the?" thread exists because the lineup confuses people who use it daily.

Skip it if your work is mostly long, heavy straight edges where you want the blade well out ahead of your knuckles. That is the Shaviv slot.

Shaviv takes the reach slot because the kit is built for it, and because the people who have run both brands professionally tend to land here. Practical Machinist ranks Shaviv as runner-up in community popularity. It describes the kit as one aluminum "A" handle, one E blade holder and three E-series blades, and says the kit is best for heavy-duty, long-reach deburring of straight edges and hole edges. The E100 is Shaviv's general-purpose heavy-duty blade, the counterpart to Noga's S10, according to both ToolGuyd and the "Looking for deburring tool NOT Noga" thread.

The most-quoted line on the subject comes from that thread: "I have used both noga and shaviv professionally, Noga is good but shaviv is awesome." That is one member's opinion from 2015, not a test. It is also the kind of opinion the whole genre runs on.

The shank sizes are the useful hard figures. In a thread on small scraper blades, members give Shaviv's E holder as taking 3.2 mm (.126 in) shanks and the B holder as taking 2.6 mm (.102 in). Those are the same two diameters Noga publishes. The same thread notes that Shaviv, Vargus and Noga each standardize on two shank sizes. That explains why a blade that looks right sometimes rattles in the wrong holder. Another thread reverses the convention and calls E-blades light duty and B-blades heavy duty. Measure the shank before you order.

Vargus, which owns the Shaviv line, offers blades in HSS, cobalt-enriched, carbide and diamond-coated versions, plus left-handed variants. It says TiN-coated blades last up to five times longer than uncoated ones. That is a vendor figure with no published test conditions. Checking it would take matched blades on the same material and edge length, counted to failure, and nobody in these sources has done that.

Price. None of the sources publish a price for the A-handle/E100 kit specifically. In a March 2026 AutomationDirect release, Shaviv's entry-level item (model 155-29081) was listed at $5.00. That tells you the floor, not the price of this kit.

The drawback. The handle. Electrician Apprentice HQ praises Shaviv's reach and calls the handle "awkward to grip" next to Noga's. Grip is the recurring dividing line in every Practical Machinist thread on the two brands.

Skip it if you mostly deburr short edges on small parts. You would be paying in grip comfort for reach you do not use.

A swivel blade will clean a hole edge, but a countersink does it faster and rounder. Practical Machinist lists deburring countersinks as their own essential category for drilled holes. Both brands make one. ToolGuyd notes Noga countersinks sized for tapped holes. AutomationDirect lists Shaviv's F-series countersinkers, which use a conical cutting geometry. Electrician Apprentice HQ describes a countersink blade with a 10.4 mm diameter among the blades it covers.

Which one to buy depends on which handle you already own. None of the sources compare the two brands' countersinks head to head or give prices. So the practical rule is to match the brand of your swivel handle, which keeps your replacement ordering in one catalog.

The drawback. It is a deburring tool, not a chamfer. MSC's knowledge-center piece says plainly that hand deburring tools cannot produce a dimensionally accurate chamfer. If the print calls out a size, the chamfer belongs in the program with the rest of the drilling and boring ops.

Skip it if your holes are rare or your burrs are mostly on outside edges. The swivel blade you already bought will get you there.

• Noga NG1 handle + S10 blades: most machinists, general bench deburring, the cheapest refills.
• Shaviv E-handle set with E100 blades: long straight edges and deep hole edges, if you can live with the grip.
• Countersink deburrer (Noga or Shaviv, matching your handle): anyone who drills and taps holes all day.

If none of these fit and you need a full multi-material drawer, AutomationDirect's March 2026 release lists Shaviv premium sets at 21 pieces (154-00024) and 12 pieces (154-90085), with universal handles, extendable holders and both B- and E-series blades. Their prices are not in these sources. The Noga RB1000 kit that shows up in searches has no published contents in these sources either, so it cannot be placed here yet. Wait for a spec sheet before buying either blind.
