How do we rank
Our AI-powered platform ranks products using multiple weighted factors from millions of products and user reviews across the web, providing the most valuable and real data. Higher scores rank first.
Quality material: Manufactured from M35 cobalt steel, with molybdenum and cobalt added to creates a hardened alloy, measuring Rockwell hardness up to 67, for much faster cutting and extra longer life span, with up to twelve times when compared with an average HSS drill bit. Precision treatment makes drills durable toughness, withstands heavy duty operation, resists corrosion and lubricates the drill bits better for cutting smoothly.
Precise & Efficient Drilling Performance: Fully Ground spiral groove design clears particles quickly,decreases friction and heat for a faster and cooler drilling performance. twist drill bits have precise diameter; M35 cobalt drill bits for hardened metal are not easy to break or wear out, ideal for heavy duty hole drilling.
Great working performance: This cobalt drill bit set is stable and not easy to break, resistant to higher heat and abrasion, and convenient as working tool. 135ｰSPLIT POINT - the 135ｰquick-cut split point are self-centering and able to penetrate metals quickly with less pressure, prevent bits from "walking and wanding". Easy cutting without need of center punch.
Split point tip increases speed. It can automatically deburr holes while drilling to keep the drill bit clean.
Much More hardness - M35 HSS is harder lot than HSS 4241, suit for drilling in stainless steel plate & quenching steel plate , iron plate, aluminum, wood.
Good Design - Triangle shank fits into power tools chuck securely and eliminates slip; two-flute design clears chips faster and allows particles to escape easily.
【Industrial Grade M35】: High-speed steel drill bit set, these drill bits contain 5% cobalt, which is much harder than the high-speed steel used in similar drill bit sets. Fully ground drill bits with smooth surface, high grinding precision, and sharp edges can reduce friction between the drill bit and the material and reduce the temperature of the drill bit during operation.
【Enhanced Precision Design】: Adopts 135° split point tip for faster penetration and less walking. Deep groove twist drill bit design ensures smooth chip evacuation and stable operation, providing accurate results for demanding work.
【Convenient Size Selection】: This 19 pcs M35 drill bit set includes everything you need to meet all your needs, bringing a user-friendly experience. Set includes: 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, 10mm [1-10mm, in 0.5mm increments].
STEP DRILL BIT FOR METAL: With a split point tip that accelerates cutting speed while preventing angled walking away from center line of bore, drilling holes in metal is fast, efficient, and clean.
SPIRAL DESIGN: The two-flute spiral grooved design deburrs chip, dust and debris for clearance and smooth cutting. With 31 step sizes, each hole made with these step bits will be precise.
PREMIUM STEP BIT: Each unibit is constructed of industrial high-speed steel with a titanium nitride coating for durability and strength to punch and drill clean holes in materials like plastic, aluminum, wood, copper, stainless steel, and other types of sheet metal.
Stability: These tough wire brush are well-filled with crimped, untempered carbon steel wire, which increases the strength of the steel wire. It has reasonable bending design of the curve to ensure that the wire will not quickly fall off during the operation of the brush wheel in the shortest time and works more smoothly.
Package Contents: You will receive 5 pieces of stainless steel wire brush for drill, the brush diameter is approx 2 "/50mm, with 1/4" diameter round handle. These wire brush drill attachments can help you tackle rusted surfaces, narrow corners, and intricate edges.
High Quality Material: This wire cup brush is made of high-quality stainless steel, brushing wire is made of high carbon steel, with excellent workmanship and durability, and excellent fixing, the wire will not be lost and bent during the intense use, able to handle both metal and non-metal surfaces effectively.
Single Size: The drill bits include 16pcs 3mm drills. If you have specific drilling size requirements, then the drill bit is very suitable for you
Quick and Efficient: The cobalt drill bit set can be used effectively on most soft and hard objects, with a 135 degree point tip and twist design for faster cutting, self-centering to prevent walk-off and faster chip and particle removal
M35 Cobalt Drill Bit: The M35 cobalt drill bit is a durable, sharp and robust drill bit suitable for cutting stainless steel, iron castings, copper, aluminum and other soft metals as well as plastics, wood etc. Note that it is not applicable to quenched bolts
