DRILL Guides
Drill guides of molded vinyl provide relief from whipping and bowing for higher speeds with less vibration. Sizes run from 0.070” (1.778mm) to 2.18” (55.372mm).
Flexible plastic Drill Guide bushings stop drill whipping and seal the chip box by stretching over the carbide drill tip and contracting onto the steel drill body. They are typically mounted in a bearing and rotate with the drill. This is our first and oldest product and is still used by many customers to maximize penetration rates, accuracy, and stop vibration. These bushings perform the same function as our SnapGuide®. Our signature Blue Bushings® guarantee you top quality.
Snap Guides
Chip Box
Flexible plastic SnapGuide® bushings stretch over carbide gun drill tip and contract over steel tube to stop drill whipping and vibration. Contoured hole in SnapGuide® forms perfect seal on gun drill. Our signature Blue Bushings® always guarantee
you top quality. 
Steadyrest
SnapGuide® with round holes are used in the steadyrest. This speeds drill loading by eliminating the need to orient the contoured hole in the SnapGuide® with the drill. Extra clearance in SnapGuide® allows drill tip to slide through easier. Also helps prevent steadyrest from being dragged out of position. 
Set Up Reduction
Each bearing holder has large drill range capacity reducing or eliminating holder change-overs on machine.
SnapGuide® Drill Range
17mm OD – <=.0769 -.5099
20mm OD – <=.0831 -.6399
30mm OD – .0985 – 1.0449
45mm OD – .800-1.5199
75mm OD – 1.520-2.044+
Chip Deflectors
Chip deflectors made of polypropylene in sizes, 078” (1.98mm) to 2.000” (50.8mm) keep oil and chips in the chip box.
Chip Deflectors stop metal chips and cutting oil from exiting the back of the chip box. They provide sealing only and no drill support. They are used on gun drill machines on short rigid drills when whipping is not a problem. They are also used in front of a Drill Guide or a SnapGuide® to extend bushing and bearing life. Chip Deflectors feature a hardened steel face bonded to a flexible polymer backing to provide perfect sealing on the drill and long life.
Collets
Collets are designed to work in conjunction with the Eldorado model “B” sharpening fixture. Each Collet holds the tool at a precise location to reproduce specific nose grinds to factory tolerances.

Gundrill Bushings
A gundrill bushing is installed in the gundrill machine’s chip box and is aligned with the spindle. It is used for diameters over .7500″ (19.05mm) replacing the GDI and GDL to support the tool into the material providing sufficient rigidity to prevent the carbide tip from chipping.
Gundrill Insterts (GDI)
A gundrill insert is required on all conventional gundrill machines from .0550″ (1.397mm) through .7500″ (19.05mm) and the tolerance is + .0002″ (.0051mm) and – 0. It is used to guide the tool into the material providing sufficient rigidity to prevent the carbide tip from chipping and to insure consistent run-out from hole to hole. The insert is replaced once it becomes oversized do to usual wear or from tool breakage. It is recommended that the drill bushing is replaced once it is 0.0005″ over the drill size otherwise inconsistent drift or tool chipping may occur.
Gundrill Liners (GDL)
A gundrill liner is installed in the gundrill machine’s chip box and is aligned with the spindle. The specified size GDI is inserted into the GDL and allows for precise accuracy for the tool to enter the material.
