Carbide and Carbide-Insert Chasers

Allen Benjamin Chasers are available in these styles:

• Solid Carbide H & G Style 100 Series
• Carbide Insert Geometric Style (Regular or Projection Styles) including "D" Style and "S-SJ" Style

All chaser cutting threads are ground from solid sub-micron carbide. Carbide insert chasers are ground and brazed onto high speed steel chaser bodies. The submicron grade of carbide permits high production threading of all ferrous and non-ferrous materials of relatively high strengths without fracturing the cutting edges, as well as yielding superior tooling life in ordinary materials.

The production life of Allen Benjamin solid carbide and carbide inserted chasers can range from 10 to 40 times that of high speed steel chasers. It is always best, when changing from steel chasers to carbide chasers, that our recommendations be carefully followed.
Allen Benjamin invites requests to quote standard and special requirements.
Pitch limits not finer than 80 or coarser than 10.

When requesting chasers, the following information is required:

1. Style of collapsible or solid adjustable tap or die head.
2. Major diameter.
3. Number of threads per inch.
4. Thread form (NC, NF, NS, etc.; Decimal/Inch and Metric; R.H. or L.H.).
5. Number of sets.
6. Angle or lead of chamfer.
7. Will chasers be threading up to a shoulder.
8. Construction number etched on die head, if known.

Allen Benjamin also offers REFURBISHED Geometric Style chasers (Regular or Projection Styles).

Allen Benjamin has been manufacturing carbide insert chasers for decades. As a service to our customers, most of whom have high speed steel chasers, we are now offering to add carbide inserts into the customer's new or used high speed steel Geometric style chasers.

Used chasers, even if completely worn out, can usually be carbide inserted and made as good as new. Used chasers are subject to inspection prior to acceptance for inserting carbide.Other considerations are:

1. Chasers must be matched set.
2. Tapped form chasers cannot be carbide inserted.
3. We remanufacture only to original size and pitch.
4. Chaser body and cam slot must be undamaged.
5. Chasers received with TiN coating cannot be properly carbide inserted and will not be accepted.
6. Carbide is not suitable for all applications.

Refurbishing chasers, in all cases, depends on the type and condition of the chaser.
The chasers must be examined and inspected by Allen Benjamin engineers before price and delivery can be determined. Contact Customer Service for details.
