Drill Masters ? Eldorado Tool is your single source for all of your precision deep or shallow hole applications. In a single pass you will achieve to print tolerances hole sizes +/- .0005? (.0127mm), straightness to .001? (.0254mm) per foot, run-out repeatability of .001? (.0254mm) per inch or better, surface finish tolerances to 32 Ra or better,
Single Flute Gundrills are available with round, kidney, and dual coolant hole configurations. Carbide tips are standard European grades which are the finest grades available in the industry today. Diameters are available from .0394? (1mm) to 3.0? (76.2mm). Lengths are available from 2? (50.8mm) to 21? (6.4m). They can be used in conventional gundrill machines as well as CNC lathes and machining centers.
Solid Carbide Single Flute Gundrills constructions consist of a single piece of carbide from the tip through the tube and brazed only at the driver transition. The result is a very rigid tool able to drill is many cases two to three times faster than a standard three piece construction tool. Diameters are available from .0394? (1mm) to .200? (5.08mm) in lengths to 10? ((254mm). Deliveries are two weeks on any size and length. The most common application for these types of tools is in the medical industry. They can be used in conventional gundrill machines as well as CNC lathes and machining centers.
Multi-diameter Step Gundrills are used to eliminate a secondary operation therefore saving valuable cycle time. In a single pass two diameters can be produced. They can be used in conventional gundrill machines as well as CNC lathes and machining centers.
Gun Reamers may be used to obtain hole ID tolerances to .0002? (.0051mm) in a single pass. The results yield surface finishes 1t 16 RMS or better. The standard application would be obtained by leaving .015? (.381mm) - .030? (.762mm) of material with the 1st drill pass then ream to the print tolerance. They can be used in conventional gundrill machines as well as CNC lathes and machining centers.
Two Flute Gundrills design incorporates two cutting edges, which reduces the chip load and increases penetration rates up to 100% in various non- ferrous applications. They can be used in conventional gundrill machines as well as CNC lathes and machining centers.
Re-Sharpening fixtures, grinding units to mount the fixtures, diamond wheels, drill collets are also available.
Gundrill machine filter bags and pump filters are in stock and always available.
Drill guides and chip deflectors are available in stock.
Delivery - We have the largest inventory of stock standard gundrills in the industry.
With over 800 stock standard diameters and lengths, 72 hour delivery on any diameter or length, standard 3 week delivery, and always blanket orders to be held on our shelves and released at your discretion.
