Forstner Bit Showdown: 5-Piece 15-35mm Set vs Single 6-100mm Bit

Compare a $13.95 five-piece Forstner bit set (15-35mm) with a $51.75 single bit listing (6-100mm range) to decide which woodworking tool fits your hole sizes.

Last updated Aug 9, 2026

Choosing Between a Forstner Bit Set and a Single Large-Format Bit

For clean, flat-bottomed holes in woodworking projects, Forstner bits are a reliable option. The decision gets interesting when you are looking at two very different ways to buy them: a five-piece set and a single-bit listing. Do you want a range of mid-size holes, or do you need a larger-diameter bit? The answer decides which woodworking tools purchase makes sense for you.

Price and Quantity Comparison

5pcs Forstner Woodworking Drill Bit Set Boring Hole Saw Cutter Wood Tools 15-35mUSD 13.955
1Pc 6Mm-100Mm Forstner Woodworking Tools Hole Saw Hinge Boring Drill Bits roundUSD 51.751

The set costs USD 13.95 and includes five bits. The single-bit listing costs USD 51.75 and includes one bit. Both are high-carbon steel bits. The real difference is how you want to cover hole sizes.

Where Each Product Wins

The five-piece set wins when you need several different diameters in one purchase. It gives you a range of common middle sizes instead of a single bit.

The single-bit listing wins when you need a large-diameter hole that goes beyond the set's upper size. It is the only option here that covers very large Forstner holes.

Product Notes

5pcs Forstner Woodworking Drill Bit Set Boring Hole Saw Cutter Wood Tools 15-35m

This set includes five high-carbon steel Forstner bits in 15, 20, 25, 30, and 35mm diameters. If you regularly drill holes in that zone, having all five sizes ready in one purchase saves you from buying individual bits. The bits are designed for clean, smooth holes and easy chip removal, which supports their use for wood, plywood, and plastics.

One limitation is the 15mm minimum and 35mm maximum. If you need a hole larger than 35mm, this set will not cover it. For a compact collection of common mid-size woodworking sizes, it is a strong option.

1Pc 6Mm-100Mm Forstner Woodworking Tools Hole Saw Hinge Boring Drill Bits round

This listing is for a single Forstner bit with a 6-100mm diameter range. That makes it the choice when your project calls for a hole much larger than the set's 35mm ceiling. The bit uses high-carbon steel, a curved-edge blade, and a round shank.

The obvious limitation is that you get one bit, not a set. If your project needs multiple hole sizes, you would need to buy another bit or use a different tool. The higher listed price fits a specific large-diameter need rather than a multi-size collection.

Final Choice by Use Case

Choose the $13.95 five-piece set if you need several common hole sizes around 15-35mm and want a ready-to-use collection.

Choose the $51.75 single 6-100mm Forstner bit listing if you are boring larger holes that the set cannot handle, and if a single bit fits your project plan better than a multi-size set.
