Sinclair Carbide Neck Expander Mandrels are made from solid carbide for precision and lubricity, reducing galling and material transfer.
The mandrels are designed .001" smaller than bullet diameter for optimal neck tension and concentricity when used before neck turning or bullet seating.
Compatible with the Sinclair Expander Die and Neck Turning Tools, these mandrels are specifically made for 30 Caliber with a diameter of 0.307 inches.
The Wilson Expanding Mandrels are specifically designed for preparing new brass cases for the seating operation.
They help achieve a consistent neck diameter on cases, which may have been damaged during bulk shipping.
Using the mandrel ensures correct neck tension, leading to more consistent seating depth and improved reloading consistency.
The Sinclair TiN Expander Mandrels offer increased abrasion resistance and lubricity due to the Titanium Nitride coating, compared to standard steel mandrels.
These mandrels are designed to be 0.001" under bullet diameter for precise neck expansion before neck turning, suitable for calibers of 7mm.
They are an intermediate option between Stainless Steel and Carbide Mandrels for users seeking durability without needing the highest-end upgrade.
The mandrels are crafted from high-grade stainless steel for precision in neck turning tools.
Expander mandrels are sized 0.001" larger than turning mandrels to ensure a perfect fit for the neck turning process.
Compatible with both NT-3000 and NT-1000 neck turning tools, as well as most older models.
The NECK TURNER PILOT is designed specifically for 0.308" bullets and is used with the Forster Case Trimmer for turning necks.
It features a carbide cutter, a hand fed cam for speed control, and a mechanical stop for length control, but is not compatible with Forster Hand Held Outside Neck Turning Tool.
Appropriate outside neck turning pilots are required for use and must be the correct caliber, with this pilot having a diameter of 0.3055 inches for 30 caliber bullets.
The Sinclair TiN Turning Mandrels offer increased abrasion resistance and lubricity compared to Stainless Steel Mandrels.
These mandrels have a Titanium Nitride coating that enhances tool life up to 10 times over standard steel mandrels.
Designed for 30 Caliber with a 0.306" diameter, the mandrels are useful for aligning the case during neck turning and setting neck tension.
Sinclair stainless steel neck turning and expander mandrels are precision-made from high-grade stainless steel and are designed for 17 to 50 caliber cartridges.
The mandrels are available in two types: turning mandrels sized .002 inch under bullet diameter and expander mandrels sized .001 inch under bullet diameter, with carbide mandrels offering even tighter tolerances.
Large caliber mandrels, suitable for 35 to 50 caliber, are compatible exclusively with the Large Caliber Expander Body and NT-5000 Turning Tool.
The Sinclair TiN Coated Turning Mandrel Kit includes an Expander Die and popular sized TiN coated mandrels for precision in neck turning and setting neck tension.
TiN (Titanium Nitride) coating offers increased resistance to abrasion, enhanced lubricity, and galling resistance compared to stainless steel mandrels.
The kit contains TiN turning and expander mandrels in various calibers (22, 6mm, 6.5mm, and 30 Caliber) all precision ground from solid carbide for tight tolerances.
The Sinclair Carbide Mandrel Kit includes Expander Die and precision ground Carbide Turning Mandrels in popular calibers for tight tolerances and concentricity.
Carbide mandrels provide increased lubricity, longevity, and resistance to galling compared to Stainless Steel.
Kits come with both Turning and Expander Mandrels in 22 Caliber, 6mm, 6.5mm, and 30 Caliber, each slightly under bullet diameter for setting neck tension.
