<p><strong>When you meet stainless steel, cast iron, or abrasion-resistant plate, ordinary tooling stalls. TTP HARD drill bits solve that problem.</strong> They mix high-speed steel with 5% cobalt, so each flute keeps hardness even as heat rises. Consequently, you can push higher speeds. The alloy also endures repeated heat cycles in production drills — resisting chipping and early dulling.</p>
<h4>Built for Performance on Hard Metals</h4>
<p>Budget bits lose temper when chips darken. Ours spread heat along the web, keeping pressure steady through HARDOX450 or stainless steel. A 135° split point self-centers, reducing the need for pilot holes and avoiding skates or gouges that force rework. That edge retention? It saves both time and money.</p>
<h4>Trusted by American Workshops</h4>
<p>From oil-field trailers in Texas to race shops in North Carolina, tradespeople trust TTP HARD cobalt bits. Tested for hardness, they perform reliably across industries. Five-star reviews back that claim. Maintenance teams and ag crews know: fewer failures means more uptime.</p>
<h4>Enhance Results with Our Cutting Paste</h4>
<p>Heat is the enemy of edge life. A dab of <a href=”/premium-metal-cutting-paste/”>CUT-IT cutting paste</a> lowers spindle load and keeps chips bright. The paste clings to flutes on both corded and cordless drills, enabling smoother exits and fewer burrs — even on stainless.</p>
<h4>Ready to Drill with Confidence</h4>
<p>Stop wasting time with bits that stall halfway. Load your kit with TTP HARD cobalt drills, pair them with our paste, and power through tough metals without drama.</p>

<p data-start=”47″ data-end=”446″>When you meet stainless steel, cast iron, or abrasion-resistant plate, ordinary tooling stalls. TTP HARDdrill bits solve that problem.

<p data-start=”490″ data-end=”1063″>Budget bits often lose temper the moment chips darken. However, our tools remain in spec because cobalt spreads heat along the web. As a result, feed pressure stays steady through thick HARDOX450, stainless. For example, technicians report cycle-time drops after switching. In addition, a 135-degree split point centers quickly, which means fewer pilot holes. In contrast, lesser bits skate and gouge, forcing costly rework. Overall, TTPdrill bits maintain hardness long after rivals have gone dull. This saves time and money.</p>

FAQ’s
Q: What are cobalt drill bits used for?
A: These drill bits are designed for drilling through hard metals like stainless steel, cast iron, and abrasion-resistant steel. They’re ideal for tough jobs that would damage regular HSS bits.
Q: Can TTP HARD drill bits cut through stainless steel?
A: Yes. TTP HARD drill bits easily cut through stainless steel thanks to their 5% cobalt content and split-point tips that reduce wandering.
Q: What are TTP drill bits used for?
A: TTP drill bits are designed for drilling through hard metals like stainless steel, cast iron, and abrasion-resistant steel. They’re ideal for tough jobs that would damage regular HSS bits.
Q: Do I need cutting paste when drilling metal?
A: Yes, using a cutting paste like TTP CUT-IT reduces heat and friction, extends drill bit life, and helps produce cleaner holes — especially on stainless steel.
