Wood Turning Chisel Set 4-Piece Kirschen 1694000

This wood turning chisel set contains four lathe chisels designed for roughing, finishing, parting, and internal hollowing. Blade widths range from 6 mm to 20 mm. Each blade is hand-forged from carbon steel and hardened in a molten salt bath to approximately 61 HRC along the entire working length. The 300 mm white beech handles provide weight behind the tool rest and stable control during cutting.

The set complies with DIN 5139 and is manufactured in Germany. The four tool types correspond to the basic sequence of most turning operations. The roughing gouge transforms a square blank into a cylinder. The skew chisel smooths surfaces and creates clean details. The parting tool separates sections or cuts sizing grooves. The curved scraper is used for hollowing the interiors of bowls and cups. The set is delivered in a cardboard sales box.

Wood Turning Chisel Set with Four Long-Handled Lathe Tools

Set Composition and Blade Geometry

Each chisel is designed for a specific stage of turning, so the four pieces function as a complete sequence rather than duplicates. The selected widths are suitable for general spindle and bowl work: a narrow 6 mm parting blade, a 16 mm skew, and two 20 mm tools for stock removal and interior scraping. The long blades allow a secure grip well behind the tool rest.

• 1609 skew chisel, 16 mm, for smoothing and fine detail cuts
• 1619 roughing gouge, 20 mm, for rough turning of round blanks
• 1629 parting tool, 6 mm, for grooves, sizing, and separating parts
• 1649 curved hollowing scraper, 20 mm, for bowl and cup interiors
• Blade material: hand-forged carbon steel
• Standard: DIN 5139

All four tools share the same handle length and blade construction, ensuring consistent balance when switching tools during a project. This is especially important for long spindle work, where hand position changes frequently. The carbon steel blades take a fine edge on a grinding wheel or stone and can be quickly honed between cuts.

Handles, Hardness, and Heat Treatment

The 300 mm white beech handles add mass behind the cutting edge, helping to dampen vibration during interrupted cuts. Hardening is performed in a molten salt bath rather than oil or water, providing even heat transfer so the blade achieves a stable structure with minimal distortion. The resulting hardness is approximately 60 to 61 HRC across the working length of the blade.

• Handle: white beech, 300 mm length
• Hardness: approximately 61 HRC over the full working length
• Heat treatment: salt bath hardening, nitrate and nitrite salt mix
• Bath temperature range: 150-550 °C depending on stage
• Austenitizing range: about 800-850 °C
• Packaging: cardboard sales box, 4 pieces

Salt bath treatment leaves the blade surface free of oil scale, reducing cleanup before first sharpening. The high hardness maintains the edge for extended use while retaining enough toughness to resist chipping under heavy pressure. Sharpen with light passes and keep the edge cool to preserve temper.

Common Applications

Semi-professional and professional turners use this set for spindle and faceplate work. Typical projects include bowls, cups, table legs, decorative columns, and turned balusters. Workshops producing craft items use the skew for finishing passes and the scraper for interior work. DIY users with a bench lathe at home benefit from having the complete basic tool sequence in one box. The 6 mm parting tool is also useful for sizing cuts before final shaping.

Catalog Technical Notes

Catalog data specifies four turning chisels with hand-forged carbon steel blades and 300 mm white beech handles, hardened in a salt bath to approximately 61 HRC, conforming to DIN 5139, and packed in a cardboard sales box. Blade widths are 16 mm, 20 mm, 6 mm, and 20 mm for the skew, roughing gouge, parting tool, and hollowing scraper, respectively.
