Construction or Car Reamers are especially adapted for heavy duty reaming as encountered in the fabrication of structural steel assemblies. They are tapered at the point to facilitate entering of holes which are out of alignment. 3-flats reduced shank

For deep hole drilling. 8" overall length. These drills are made with a general purpose flute design which will perform well under the widest range of operating conditions and materials. Long flutes allow better chip evacuation in deeper holes.

SDS Plus. 4x90 head geometry prevents locking when hitting rebar on the side. Bit is designed for longer life when drilling in concrete. As an additional benefit, it can crush through and pulverize rebar when drilling in reinforced concrete applications.

Heavy-duty construction makes these drills suitable for more demanding applications. Designed for efficient drilling in stainless steel and tougher ferrous materials. The 135°split point reduces the thrust requirements and minimizes walking. Black & Gold

Straight Flute “Hand Taps” are the most popular and versatile style of taps in general machine tapping operations. They are for general use in production tapping or hand operations in a wide range of application material groups.

Adjustable straight handle tap wrenches have one threaded handle which is attached to one of the clamps. The clamp is opened to insert the tool and then tightened down against the tool to secure it. Used with larger taps, reamers or screw extractors.

200/240/280 series drills are designed for general purpose drilling under a wide range of conditions. For low to medium tensile strength materials. The surface treatment prevents chip welding, improves chip flow and increases abrasion resistance.

200LH drills are used in close center multiple spindle gear driven drilling heads, where adjacent spindles operate alternately left and right hand.  They are also used in left hand screw machines.  Can be used to drill out broken bolts.

Oversize taps are similar in design to a standard tap, but with a pitch diameter that is usually 0.0050” to 0.0055” larger than standard. Oversize taps are used primarily where a part will be plated or treated after tapping.
