The TiN coating extends tool life when machining ferrous metals. It is commonly used in general manufacturing and maintenance applications.

What are the specifications of the KEO 51751-TIN countersink?

The KEO 51751-TIN countersink has a 1 3/4 in body diameter, a 3/4 in shank, and three flutes. It is made from TiN coated high speed steel with a 110° included angle. The manufacturer part number is 51751-TIN. This general-purpose tool is designed for use in drill presses and handheld drills.

Where to buy the KEO 51751-TIN countersink worldwide?

You can source the KEO 51751-TIN countersink through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time. We supply this KEO tool to procurement teams and maintenance shops internationally.

How to select the correct KEO countersink for your application?

Select a KEO countersink based on the required countersink angle (110° for standard flathead screws), material hardness (TiN coating for steel), and shank size matching your tool holder. The 1 3/4 in body diameter suits larger holes. For softer materials, uncoated HSS may suffice. Always match flute count to desired finish quality.
