Step Drill Bits: When to Use Them and How to Pick the Right One
Step drill bits cut clean, burr-free holes in sheet metal and thin materials without pilot holes. Learn how to choose the right step count, size range, and coating for your application.
118° vs 135° Point Angles: Which Drill Bit Geometry Cuts Better?
The point angle on a drill bit determines how it starts, how much thrust force is needed, and what materials it cuts best. Learn when to choose 118° conventional points versus 135° split points.
TiN, TiAlN, or Black Oxide? Drill Bit Coatings Explained for Industrial Buyers
Drill bit coatings affect tool life, cutting speed, and cost. This guide breaks down TiN, TiAlN, black oxide, and bright finish options so you can match the coating to your workpiece material.
HSS Drill Bit Shank Types Explained: Straight, Taper, and Reduced
The shank is how a drill bit connects to your machine. Straight, taper, and reduced shanks each serve different purposes. Learn which shank type fits your chuck, machine, and application.
How to Extend Drill Bit Life: Speed, Feed, and Coolant Best Practices
Most drill bits fail prematurely due to incorrect speed, excessive feed pressure, or inadequate cooling. Learn the practical rules for RPM, feed rate, and coolant that maximize tool life and cut cost per hole.
M2 vs M35 vs M42 HSS: Which Drill Bit Grade Do You Actually Need?
Not all high-speed steel is the same. Learn the real differences between M2, M35, and M42 grades — hardness, heat resistance, cost — so you can spec the right drill bit for your application.
Twist Drill Bit Anatomy: Understanding Flutes, Margins, and Web Thickness
Every part of a twist drill bit serves a purpose. Understanding flutes, margins, web thickness, and helix angle helps you choose the right bit and troubleshoot drilling problems faster.
Bi-Metal Hole Saws: How to Choose the Right Size, Teeth, and Material
Bi-metal hole saws combine HSS cutting teeth with a flexible spring steel body. Learn how to select the right tooth material, diameter, and pitch for wood, metal, stainless, and plastic applications.
DIN 338 vs DIN 340 vs DIN 345: Drill Bit Standards Decoded
DIN 338, DIN 340, and DIN 345 define the three most common HSS drill bit configurations. Learn what each standard specifies and how to choose the right one for your drilling application and equipment.
From Steel Smelting to Finished Drill Bits: Why Vertical Integration Matters
JacoTools controls every step from HSS steel smelting to finished drill bits. Learn why vertical integration delivers better traceability, consistency, and pricing for industrial cutting tool buyers.
