HIGH SPEED STEEL: These metal drill bits for steel are made of high speed stainless steel and is designed to ensure sharp and fast execution in any material leaving clean results. This 8-piece drill-bit set is capable of drilling through plastic, copper, stainless steel, and other surfaces.

LARGE DRILL BIT SET: Heat treated carbon steel with a black enamel coating is durable and can withstand heavy duty operation for a long tool life.

PRECISION DRILLING SET: Bit is precision ground with geometry of 135-degree split point for quick self-centering penetration and an accurate start that prevents walking and clears chips and particles faster.

Premium cobalt high speed steel construction for proven capability and durability to drill holes in wood, plastic, aluminum, copper, stainless, sheet metals and many other types of materials

Superior gold titanium and black nitride dual coating finish holds up lubricant better for smoother drilling, and is 80% more durable and corrosion resistant than regular black enamel finish

135° Split point design at tip increases cutting speed with self-centering feature and prevents drill walking or wobbling

High Quality Material - High Speed Steel M2 Black and Gold, resists corrosion, ensures outstanding durability, sharpness and capability, reduces the friction and runs cooler.

Black and Gold Oxide Finish - Premium gold titanium and black nitride dual coating can apply lubricant better for smoother drilling and is more durable and corrosion resistant than the regular black surface.

135-degree & Split Point - Increases cutting speed with self-centering and prevents walking, clears chips and particles faster. The split point tip can increase the wear resistance. 135-degree penetrates hard material without a pilot hole and produces small chips to reduce clogging.

DRILL-BIT SET: Our Silver and Deming Drill-Bit Set is professionally built for personal or industrial use. This 8-piece drill-bit set is capable of drilling through plastic, copper, stainless steel, and other surfaces.

HEAVY-DUTY DRILL BITS: With a premium high-speed steel construction, these drill bits for metal, plastic, and wood have a unique black-and-gold dual finish to hold lubricant for smoother drilling while providing maximum corrosion resistance.

PRECISION DRILLING SET: Each drill bit has a 135-degree split-point design that increases cutting speed and makes any drill fast and efficient. The self-centering feature helps prevent walking or wobbling on the bit while in use.

Set of 8 pieces; 1/2" shank; Made of M35 - high-speed steel + 5% cobalt

Silver and Deming drill sets in a fitted plastic box

Sizes include 9/16", 5/8", 11/16", 3/4", 13/16", 7/8", 15/16" and 1"

POINT DESIGN: 135° split point design increases cutting speed with self-centering feature and prevents drill bit walking or wobbling on working surface.

REDUCED SHANK with THREE FLATS: 1/2" reduced shank drill bit with tri-flat is designed to eliminate drill bits spinning in the chuck and ensures grip. Superior black oxide finish offers great wear resistance.

WIDE FLUTE: Parabolic flute design improves chips removal and prolongs drill bits life while drilling in metal and wood.

M35 HSSCO High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance.

Black and gold polished treatment adds lubricity and creates small pockets on the surface of the tool that act to hold coolant near the cutting edge.

135-Degree split point for accurate centering and fast penetration and round shanks allow use with a wide variety of toolholding systems.

HSS HIGH SPEED STEEL: The high-speed steel material these bits are made of are designed to ensure sharp and fast execution in any material for clean results while making the bit long-lasting, durable, and wear resistant.

135° SPLIT POINT DRILL TIP: The 135-degree split point increases cutting speed with self-centering with no pilot hole and prevents walking while clearing chips and particles faster.

1/2” TRI-FLAT SHANKS: The tri-flat on the shanks of these drills are constructed for tighter chucking to maximize the hold to create precision holes.
