Extra-long air chisel bits help reach recessed, awkward, or distant work areas without requiring a standard-length bit. The best choice depends on shank compatibility, bit length, and tip style: the 18-inch two-piece set suits buyers who want a pointed and flat chisel, while the three-piece sets offer more tip options. The 17.7-inch assortment is better for buyers who also need a scraper.
| Product | Length | Set Includes | Best For |
|---|---|---|---|
| Four-Piece Air Hammer Set | 17.7 inches | Flat, scraper, and pointed styles | Tip variety |
| Two-Piece Cr-Mo Set | 18 inches | Pointed and 3/4-inch flat chisels | Two essential tips |
| Two-Piece Cr-Mo Set | 14 inches | Pointed and 3/4-inch flat chisels | Long reach with less length |
| Three-Piece 42CrMo Set | 18 inches | Point, taper punch, scraper, spring | Extended-reach workshop tasks |
| Three-Piece Taper Punch Set | 18 inches | Two point sizes and a flat chisel | Pointed-tip options |
Four-Piece Set With Scraper
This 17.7-inch assortment is best for buyers who want several attachment styles in one set. The listed tools include a flat chisel, a 2-inch scraper, and pointed options. The product description identifies 45# carbon steel as the material and describes the bits as reusable.
Choose this set if scraping and general chiseling are both part of the job. Its 2-inch scraper is wider than the listed flat chisel, making the assortment useful when different contact widths are needed. The product details do not specify a shank diameter, so check the attachment requirements of your air hammer before ordering.
18-Inch Two-Piece Cr-Mo Set
This set is best for buyers who need two core bit shapes in an extra-long format: a pointed chisel and a 3/4-inch flat chisel. Both tools are 18 inches long and have a listed 0.401-inch shank. The manufacturer describes the material as 42Cr-Mo alloy steel that is heat-treated for impact resistance and wear resistance.
Choose this option if your air hammer accepts a 0.401-inch shank and you do not need a scraper or multiple point widths. Its two-piece selection is straightforward, but it offers fewer tip styles than the larger assortments.
14-Inch Two-Piece Cr-Mo Set
This 14-inch version is best for buyers who want added reach but prefer a shorter tool than an 18-inch bit. The set contains a pointed chisel and a 3/4-inch flat chisel, both with a listed 0.401-inch shank. Its 42Cr-Mo alloy steel construction is described as heat-treated for toughness and resistance to repeated impacts.
Choose it if the 18-inch sets are longer than your work area requires. It provides less overall reach than the 18-inch alternatives, so it may not suit tasks where maximum extension is the main priority. Confirm that your air hammer accepts the specified shank size.
18-Inch Three-Piece Set With Spring
This set is best for buyers working in tight or awkward areas who want three different working ends. It includes a 3/4-inch scraper, a 3/8-inch taper punch, a 1/8-inch point bit, and an air hammer spring. The manufacturer lists 42CrMo steel and describes the tools as heat-treated for shock resistance.
The extended length is presented for access around areas such as truck frames, hydraulics, and ceilings. Choose it if a scraper and two narrower point styles are useful. The listed product details do not state the shank diameter, so verify fit with the tool manufacturer before purchase.
18-Inch Three-Piece Taper Punch Set
This set is best for buyers who want two pointed tip sizes alongside a flat chisel. Its three 18-inch tools include a 0.22-inch point tip, a 3/8-inch point tip, and a 3/4-inch flat chisel. The listed shank size is 0.401 inch, and the product description identifies Cr-Mo alloy steel.
Choose this set if pointed work is a priority and a scraper is not needed. Its three-piece selection focuses on punch and chisel shapes rather than broad scraping. Check that the 0.401-inch shank matches your air hammer.
Buying Guide: How to Choose Extra-Long Air Chisel Bits
Which length should you choose?
Compare the bit length with the distance and clearance involved in your work. The 18-inch options provide the greatest listed reach in this selection. The 17.7-inch set is close in length, while the 14-inch set is a shorter alternative. Extra length can help reach recessed areas, but it does not replace checking whether the tool can be controlled safely in the available space.
Does the shank fit your air hammer?
Shank compatibility is essential. Three products list a 0.401-inch shank; the other two product descriptions do not give a shank diameter. Confirm your air hammer’s required size and the bit’s specifications before buying. Do not assume that similar-looking bits fit the same tool.
Which tip style fits the task?
- Flat chisel: A general choice when a wider edge is needed.
- Pointed bit or taper punch: Useful when the task calls for a narrower contact point.
- Scraper: The relevant choice when the listed job involves scraping or broad material removal.
Also compare the number of tips in each package. Two-piece sets cover a pointed and flat option, while three- and four-piece assortments add more variety. A larger set is not automatically better if its included shapes do not match the task.
What should you check about material?
Compare the stated materials and construction claims, but treat them as product specifications rather than guarantees of performance. The listings identify 45# carbon steel or 42Cr-Mo/Cr-Mo alloy steel, with some descriptions mentioning heat treatment. Review the individual product details for the exact material, shank size, and included pieces.
