who we are

Over 30 Years Experience

Lammers Microdrill is a small business consisting of a core group of individuals who have over 30 years experience building and using small metal bond diamond tools. We pride ourselves on building the finest quality small tools on the market.

Lammers Microdrill started in the late 1980’s to fill the need for small precision diamond core drills under 1/8” in diameter in certain industries such as aerospace and medical devices. Over the past 30+ years, Lammers Microdrill expanded into various styles of small metal bond tools with a principal focus on building the toughest tools available under ½” in diameter. The success of the company is built on a foundation of technical ceramic machining requirements knowledge and a tried-and-true formula for building small diamond tools.

On Small Tools

All of the tools currently built by Lammers Microdrill consist of diamond grit abrasive impregnated in a metal bond. The small size of the tool requires us to start with the best materials available and build to very strict quality standards, with tight tolerance and zero runout being the norm. We optimize tools for use on the following common materials as well as many other tough-to-machine nonmetallic materials.

Aluminas
Quartz and Glass
Sapphire
Carbides such as Silicon Carbide, Boron Carbide, and Tungsten Carbide
Zirconia
Piezoelectric materials
Natural stones and minerals
YAG
Beryllia
Various Composite Materials
MACOR
Nitrides such as Aluminum Nitride, Boron Nitride, and Silicon Nitride

These tools are either sold as unmounted with just the diamond section and drill tube, or as a mounted tool based on the customer’s requirements.

Common adapter mounts include Branson, 1”-14 female, 7/8”-14 female, 3/4"-16 female, 5/8”-18 female, Belgian, and Habit.

Most common shank sizes in both brass and steel are also available for mounting. Tight tolerance centerless ground shanks can be specified when required. 5/8” OD centerless ground steel shanks for OptiPro machines also an available option.

CORE DRILLS

Small high-quality metal bond core drills are the flagship product at Lammers Microdrill. Our core drills are manufactured using thin wall stainless steel tubing to minimize the wall thickness of the drill and prevent oxidation of the drill tube. Sizes range from .023” OD to .475” OD

ID critical drills can be manufactured with .010” ID to .386” ID.
Standard Tolerance is ±.001” OD/ID. Our tightest tolerances are ±.00025” OD and ±.0005” ID.
Diamond grit and bond can be selected based on material and machining requirements.
ID features such as waterways or flats are also available for both ID and OD drills.

Deep drilling depths

Lammers Microdrill specializes in extra-long core drills with drilling depths up to 24.”

These drills have historically been used in the manufacturing of gas laser tubes, but they can have applications in other manufacturing processes such as laboratory glassware.

ROUTER TOOLS

All Lammers Microdrill router tools greater than 1/16” feature a unique hourglass slot in the face to aid in the flow of coolant and swarf removal. Hourglass slots can be placed on center for side milling or offset for plunge milling.

Coolant holes can be added to tools greater than 1/8” for pushing coolant through the tool. These tools feature a thick wall tool steel tube to withstand side pressure from milling.

Router tools with a .0225” -.050” OD are solid tools with no slot on the face.

SPECIALTY TOOLS

Lammers Microdrill can make the following specialty tools under .475” OD

Disintegrating drills with an offset coolant channel for creating blind holes with flat bottoms. These tools can be made with thick wall steel tube for milling as well as drilling.
Small solid tools and reamers down to .023” OD commonly used for milling small pockets, removing corner radiuses, or reaming a hole to a precise size.
Small mounted wheels with carbide shanks for ID grinding.
Generating and radius milling tools for creating convex shapes.
Counterbore tools with a specific OD and ID.
Chamfer tools with an included angle ground on the face of the tool. These can be made with or without a coolant hole.
Double drills or dual core drills commonly used for creating toroid shapes.

WATER SWIVELS

Water Swivels are used to add tool thru-coolant capabilities to machines that are not equipped with a through spindle coolant feature.

Lammers Microdrill offers a full-size water swivel as well as a “mini” water swivel for light duty applications.

Lammers manufactures water swivels using high-quality components. New units will not have any measurable runout.

Full size water swivels feature a 7/8” shank and accept a Branson mount or 5/8”- 18 female adapter.

Mini water swivels feature a 1/2” shank and accept a Branson mount or 3/8”-24 female adapter.
