Countersinks

Lightning Bolt is a wholesale distributor of Drillco™ and Walter™ countersinks. We carry general purpose countersinks such as single flute, 3-flute, 4-flute, 6-flute and fluteless. We also carry heavy-duty countersinks like Walter's 4-flute with exclusive ICECUT™ coating. This unique coating reduces frictional heat and optimizes tool life. Plus, this heavy-duty Tool sports thicker teeth which gives it added stability.

Please contact us if you would like a demonstration of any Drillco™ or Walter™ product.

Single Flute

60◦ for centering
82◦ for Countersinking flathead screws
90◦ for chamfering and deburring
100◦ for making screw and rivet holes

4-Flute

These heavy-duty ones feature ICECUT™ coating made of ALCrN. It provides greater heat resistance which prolongs its life. The 82◦ point angle works beautifully for countersinking, deburring and chamfering steel, stainless steel, and non-ferrous metals.

Deburring Tools

Fluteless deburring tools use an angled hole that passes through the center of the tool to reduce vibration and chatter. This creates smooth cuts and prevents chips from clogging the tool.
