Groz 5-Piece Long Drive Pin Punch Set, 8" Round Shank Carbon Steel Punches with 3-3/4" Pins, 1/8" 3/16" 1/4" 5/16" 3/8", Vinyl Pouch (25508)

Stop fighting stuck pins in deep bores with punches that are too short for the job. The Groz 25508 long drive pin punch set runs 8" overall with a 3-3/4" working pin, giving you the reach to push roll pins, dowel pins, and keys all the way through deep housings on engines, transmissions, firearms, and industrial machinery.Each punch is built from carbon steel, induction hardened and tempered to 52-58 HRC, and finished in rust-inhibiting black oxide. The two-piece construction is the key feature of this length — the pin and body carry separate hardnesses, which minimizes head peening and keeps the long, slender pin straight over the life of the tool. The round shank carries clean, well-cut knurling for a positive finger grip, and the square striking head gives your hammer a flat target for accurate strikes.The set includes five of the most-used sizes — 1/8", 3/16", 1/4", 5/16", and 3/8" pin diameters — packed in a roll-up vinyl pouch that fits in a tool drawer or service cart. Suitable for automotive technicians, gunsmiths, machinists, millwrights, and serious DIYers who need long-reach punches that hold up to continuous use.

• REACH DEEP BORES THAT SHORT PUNCHES CAN'T - 8" overall length with a 3-3/4" pin drives out roll pins, dowel pins, and keys from deep housings where standard 4" and 6" punches bottom out before the pin clears.
• TWO-PIECE BUILD MINIMIZES HEAD PEENING - Separate body and pin construction lets each section carry its own hardness, so the striking head resists mushrooming while the long pin stays straight under repeated hammer blows.
• HARDENED CARBON STEEL FOR HEAVY USE - Induction-hardened and tempered to 52-58 HRC carbon steel withstands continuous shop use, and the rust-inhibiting black oxide finish keeps the punches protected between jobs.
• POSITIVE GRIP, ACCURATE STRIKES - Round shank with cleanly cut knurling gives a non-slip finger hold for controlled placement, and the square striking head delivers a flat, predictable target for your hammer.
• FIVE COMMON SIZES IN A VINYL POUCH - Set covers 1/8", 3/16", 1/4", 5/16", and 3/8" pin diameters for automotive, gunsmithing, machinery, and general fabrication work, organized in a roll-up vinyl pouch for the toolbox.
